portable: add repo version to main string

When compiling got-portable from source, outside of an official release
tarball, it's often helpful to know which commit the binary was built
from, especially for diagnostic purposes.

This adds an extra hook to AC_INIT to derive whether -portable is being
built in-tree or via a release tarball.
