[OE-core] [PATCH 4/4] relocatable: add file existence checking in relocatable_native_pcfiles

[Jiang Lu]

Some package may create a ${libdir}/pkgconfig directory in its sysroot
without .pc file. It leads following error:
sed: can't read ${sysroot}/${libdir}/pkgconfig/*.pc: No such file or directory

To avoid this, add a file existence checking in relocatable_native_pcfiles()
before sed.
