libstdc++: Remove noexcept-specifier from MCF __cxa_guard_acquire [PR116857]

This function definition should not be marked as non-throwing, because
the declaration in <cxxabi.h> is potentially throwing.

Also fix whitespace.

libstdc++-v3/ChangeLog:

	PR libstdc++/116857
	* libsupc++/guard.cc (__cxa_guard_acquire): Remove
	_GLIBCXX_NOTHROW to match declaration in <cxxabi.h>.
