community/lua-lgi: Remove bashisms to enable build

Lua-lgi package was using some illegal bashisms which should prevent building. There is a commit hook, but somehow it was managed to be skipped and thus the package was not properly build any longer.

What is even more worry some, is that these changes did not get automatically get caught.

For example, when installing lua-lgi and lua5.1, the lua5.1-lgi package is supposed to be installed. By removing the bashisms we can now properly build lua-lgi again.
