Provisioning: Set macOS locale to "en_US.UTF-8"

The 419f42903154489e2dace8d1eba183036275448b commit in qtbase
introduced a regression where the tst_fusion test in qtqtuickcontrols2
hits a deadlock while trying to print a warning about a non-UTF-8
locale.

The warning is due to the fact that the agent executed in Coin's VM
does not have an explicit locale set, and thus it defaults to "C".
There is no explicit locale set in any .bashrc (or similar files),
and neither in any launchd configuration (because the agent is
executed at macOS startup via launchd).

The deadlock is due to trying to acquire the same lock twice while
trying to write output to stdout.

The test only deadlocks on CMake configurations, and not qmake
configurations, because Coin has a hardcoded instruction to set the
locale to UTF-8 when running qmake tests.

Until the deadlock situation is addressed in another change, the issue
can be fixed by setting the macOS configuration locale to UTF-8
explicitly, by assigning the LANG environment variable
into ~/.bashrc at provisioning time, like we do with other environment
variables like PATH.
