package/libv4l: allow build of v4l2 utilities on noMMU platforms

This commit removes the dependencies on MMU and dynamic libraries.

In order to build v4l2 utilities such as compliancy tools like
v4l2-compliance or cec-compliance, v4-utils can now be built without
dynamic libraries support.

In that case the v4l-utils parts which depends on dynamic library
support are not built:
 - libv4l & libv4lconvert libraries
 - libv4l plugins
 - rds-ctl utility
 - contrib test utilities

The rest of the utilities are built.
