Improve shebangfix framework

- Support multiple values in *_OLD_CMD, i.e. we can now fix both "/usr/bin/python" and "/usr/bin/env python" at the same time
- Default *_OLD_CMD values are now always appended, so you don't need to specify them in individual ports
- Add lua support (depends on USES=lua)
- Add more default values, such as "/usr/bin/env foo" for python, perl, bash, ruby and lua
- Shebangfix now matches whole words, e.g. we will no longer (erroneously) replace "/usr/bin/perl5.005" with "${perl_CMD}5.005" (but "/usr/bin/perl -tt" is still (correctly) replaced with "${perl_CMD} -tt")

Note that *_OLD_CMD items containing spaces must now be quoted (e.g. perl_OLD_CMD=/bin/perl /usr/bin/perl "/usr/bin/env perl")

Update shebangfix usage according to new rules in many ports:

- Remove *_OLD_CMD for patterns now replaced by default
- Quote custom *_OLD_CMD which contain spaces

Fix shebangfix usage in many ports (irrelevant to infrastructure change):

- Remove redundant SHEBANG_LANG (no need to duplicate default langs)
- Remove redundant *_CMD (such as python_CMD=${LOCALBASE}/bin/python${PYTHON_VER} when USES=python is present)
- Never use *_OLD_CMD in REINPLACE_CMD matchers, these should always look for exact string
