Some .fex files (for instance those for the H6 in sunxi-boards) contain a trailing semicolon on some lines, after the end quote of a string value. This confuses the parser and messes up our "make check" tests, so remove the semicolon both in the parser, but also in the unify-fex test conditioning tool, to make the tests pass.
