Fixes Telephony ProgressDialog to use system theme

PhoneUtil has to do explicit work when creating dialogs
to inherit system themes. It does that work across the
various AlertDialogs, but doesn't do the work for
ProgressDialogs, causing system-dependent (currently
watch only) configurations to be lost. This change adds
the explicit setting of themes to those Dialogs.
