math: Fix test-fenv.c feupdateenv tests

Browse Source 
The feupdateenv tests added by 802aef27b2 do not restore the floating
point mask, which might keep some floating point exception enabled and
thus make the feupdateenv_single_test raise an unexpected signal.

Checked on x86_64-linux-gnu and aarch64-linux-gnu (on Apple M1 trapping
is supported).
