package/btrfs-progs: install to staging directory

Other packages when building against btrfs-progs require headers in the
staging directory under /usr/include/btrfs. This patch enables
installing btrfs-progs to the staging directory to enable other packages
to build against the btrfs-progs headers.

[Thomas: take into account the BR2_STATIC_LIBS case, by adding the
relevant BTRFS_PROGS_INSTALL_STAGING_OPTS variable, as well as a patch
to make sure "install-static" installs the static library and the
headers.]

+Subject: [PATCH] Makefile.in: install static library and headers in
+ install-static
+
+Currently, the install-static target only installs the statically
+compiled tools. However, some programs outside of btrfs-progs (for
+example docker) link with the btrfs libraries. If such programs want
+to link statically against the btrfs-progs library, then this library
+should be installed by "install-static". Indeed, "make install" cannot
+be used if the support for shared library is not enabled.
