Move redirect2null() out of posix extensions but preserve compatibility

posix.redirect2null() is a decidedly rpm-specific, it should've really
always been rpm.redirect2null(). Move the code to rpmlua.c and make
it available in the rpm-namespace, but to preserve script compatibility
add it to the posix module too.

One step closer to unforking the posix extensions which is more or less
a pre-requisite for ticket #165.
