qa/common.rc: big hammer for LC_COLLATE
qa/common.rc: big hammer for LC_COLLATE

It turns out that on some platforms the RE [A-Z] really means [A-Za-z]
by default ... we use this all over in QA.  While this (based on how
long has been lurking) is mostly benign, it does bite in some places,
like qa/1071 that will fail on some platforms but only in June or July
... no, I'm not joking!

Setting LC_COLLATE=C in the environment enforces the original Unix
semantics that was prevailing when most of the QA tests were written
and returns us to a sane place.
