Ensure GAP (and PYTHON) uses an absolute path

If a user does GAP=./some/relative/path/to/gap then it works for the initial sanity check, but no more once we changed into tmp/pkgdir/.
We should handle this. Either by rejecting such paths, or (nicer) by turning them into absolute ones.
But be careful to still handle actual absolute paths, and also things like gap which are relative to PATH.
Perhaps this simple rule would already work: if there is a slash in $GAP but not at the start, then it is a relative path; fix that by prepending $PWD/.
