crossdev/emerge-wrapper: merge repos.conf parsers

The crossdev code had a more full-featured parser of the repos.conf output
than the emerge-wrapper.  The latter failed to include the last overlay in
the list leading to ugly warnings like:
/usr/bin/emerge-wrapper: line 48: /eclass/toolchain-funcs.eclass: No such file or directory
/usr/bin/emerge-wrapper: line 49: tc-arch: command not found
