rpm: fix expansion of %_libdir in macros

There is a patch in oe-core[1] to avoid hardcoded paths in macros. It
tries to use libdir to expand %_libdir in macros.in. However, in
upstream commit[2], libdir for macros in CMakeLists.txt is set to
${prefix}/=LIB=, which causes %_libdir to expand to ${prefix}/=LIB=
instead of the correct path in the final macros.

On target:
$ rpm --showrc | grep _libdir
[snip]
-13: _libdir    ${prefix}/=LIB=
[snip]

This also causes %__pkgconfig_path in fileattrs/pkgconfig.attr to become
an invalid regular expression when building rpm packages. This results a
warning in log.do_package_write_rpm in all packages:

Warning: Ignoring invalid regular expression ^((${prefix}/=LIB=|usr/share)/pkgconfig/.*.pc|usr/bin/pkg-config)$

Set libdir to ${CMAKE_INSTALL_FULL_LIBDIR} instead of ${prefix}/=LIB= to
make sure it is expanded to the correct path in macros.

After the patch:
On target:
$ rpm --showrc | grep _libdir
[snip]
-13: _libdir    /usr/lib
[snip]
