OS X QSettings auto test/writing check update

This patch aims to provide an updated test that follows changes started
in 10.7: new rule is that only root can access SystemScope settings. It
also disables the sync() workaround code path which is at least not
executed during the tst_QSettings execution and returns wrong value to
the test.

From Apple's documentation:
"Note that modification of some preferences domains (those not
belonging to the “Current User”) requires root privileges (or Admin
privileges prior to OS X v10.6)—see Authorization Services Programming
Guide for information on how to gain suitable privileges"

[ChangeLog][QtCore][QSettings] QSettings now returns the correct value
for isWritable() when using SystemScope settings.
