[Glamor] [PATCH] Rework pkgconfig files using "Requires".

[Drew Moseley]

The current method of building the .pc files via autoconf substitutions
embeds full paths directly into the files.  With a cross-built sysroot
this may or may not be the right path.  Specifically with a Yocto build
the sysroot where glamor was built may not be in the same location when
a package using it is built.  This patch modifies the generated .pc
files to use "Requires" rather than embedding the dependent package
settings.
