ola: bump to 0.9.3

This update requires a few changes. First, good news, the patches that you
guys have submitted to OLA have been merged, so we can drop those:

 ola-0001-fix-build-warning.patch -> ea375582b0bfee93d66608ffc807078ffc48e961
 ola-0002-move-python-sub-check-to-configure.ac.patch -> 673a7602a6bf7a6aa8a8461ebd9362d59f6e21df
 ola-0003-fix-check-for-python-module-for-cross-compilation.patch -> b51b48be81ec38bc7d1229be0c7d3189c5ddbafa

Less good news: OLA now builds a small protoc wrapper (ola_protoc) that is
built and executed at compile-time on the host. If we don't change anything,
ola_protoc is built with the target toolchain and therefore can't run on the
host. Explanation for ola_protoc is here

To solve this, I created a package host-ola, which builds and provides an
ola_protoc for the host. It tries to disable as much as possible of things
that we won't need at configure time. Only ola_protoc is built and installed
so it's not that long.

The change has been built-tested only.

[Thomas:
 - add HOST_OLA_DEPENDENCIES variable, so that host-ola doesn't get
   all the dependencies of the target ola package: certain target ola
   dependencies do not have corresponding host packages (and it
   doesn't make sense to have them as dependencies just to build
   ola_protoc)
 - improve the commit log to mention which upstream commits correspond
   to our patches.]

-    configure: add option for user to override checks for Python modules
-    
-    The check for google.protobuf is inherently flawed for cross-compilation,
-    as it uses the host Python to check for target modules.
-    
-    In this case, it is not possible to check for a Pyhon modules altogether,
-    and we need to rely on the user to properly tell us whether we do or do
-    not have google.protobuf.
-    
-    This is done by adding am autoconf cache variable:
-        ac_cv_have_pymod_google_protobuf
-    
-    which can be set to:
-      - yes     : force the test to be true
-      - no      : force the test to be false
-      - (empty) : let the test decide
-    
-    This is then used in AX_PYTHON_MODULE to override the test.
-    
-    Currently, only the google.protobuf Python module is checked for, but
-    the same could be done later on of other Python modules that may be
-    added in the future, of course.
-    
-    Fixes configure-errors like:
-        http://autobuild.buildroot.net/results/e63/e634d5f0cee3967caffaa6e7ada8c0968e3eff63/build-end.log
-    
-    Also fixes some under-quotation in the python module check.
