Correct qcollator_posix.cpp's check against system locale

Browse Source 
The check was made against the default locale but the code calls the
system functions (wcscoll, wcsxfrm, wcscmp) for locale-specific
collation, so should be comparing to the system locale's collation
locale (i.e. LC_COLLATE). Also correct the Android-only check in
tst_QCollator::compare() which duplicated the check but neglected the
C locale, which is also supported (via QString::compare).
