gspawn, tests: check passing special chars in args

The existing singlethread g_spawn_sync test is modified and now tests
that special characters in arguments are correctly passed to child.
The test is added before spawn escaping fixing on win32
and covers the case currently broken on win32:
'trailing \ in argument containing space'.
