xcompile: crossgcc lookup in parent paths, for painless libpayload support

libpayload is calling the xcompile script from payloads/libpayload, so the
script never finds the path on its own and has to be fed the right XGCCPATH by
hand.

This makes xcompile look for the parent path too, so that it can find the
crossgcc toolchains when called from libpayload.
