Make the names inside the .pc files match the pc filename

As far as I can tell this is purely cosmetic, but it should probably match nonetheless.

Testing Done:
ran `PKG_CONFIG_PATH=$(pwd)/meson-private pkg-config --modversion` from the build directory with and without the patch and made sure there was no difference.
