libnm-glib: work around possible compiler bug with GValueArray deprecation workarounds

Browse source 
GValueArray is deprecated.  Unfortunately, it's part of our API right now,
so we have to keep it around for a while.  But since it's deprecated, and
we want to know about *other* deprecations, we have to suppress deprecations
about GValueArray.  Unfortunately using macros to do that (eg in
nm-gvaluearray-compat.h) exposes some compiler bugs due to the combination
of parentheses/braces and #pragma from G_GNUC_BEGIN_IGNORE_DEPRECATIONS,
resulting in warnings like:

nm-utils.c:920:9: error: expected expression before ‘#pragma’

Work around this by not trying to stuff what's now a macro (eg
g_value_array_get_nth) into what's already a macro (G_VALUE_TYPE).
There's probably a better way to do this...
