    tools: append to the perl path so that it stays overrideable. Fixes #604892
    
    We were prepending datadir to the INC path for perl to find gtkdoc-common.pl.
    This also caused the unit tests to run with the installed version, despite
    that we had set an local path to INC from the Makefile.
