[OE-core] [PATCH 2/5] relocatable: Make native .pc files relocatable

[Richard Purdie]

The native .pc files currently have hardcoded paths in them meaning each has
to be relocated at final install time. pkg-config has built in functionality
to avoid this, namely the pcfiledir variable.

This function translates .pc files to use the variable meaning further
relocation later is unnecessary.
