bitbake.conf: Assign SRCPV so that it will be tracked correcting in the sstate checksum

Currently, SRCPV is just listed as having a value of ${@bb.fetch2.get_srcrev(d)}
which isn't helpful. This can mean that if PV changes, two recipes can have the
same sstate checksum despite having different PV values since the PV value itself
isn't tracked anywhere.

Adding this line means that the real PV value is expanded and recorded in the sstate
checksum, meaning the sstate packages no longer overlap. This is critical in ensuring
consistent builds for revipes using SRCPV.
