tests: Only use g_mkstemp() in /tmp rather than current directory

Browse Source 
It’s not entirely clear from the documentation, but `g_mkstemp()` (and
`g_mkdtemp()`) operate in the current directory, rather than the system
temporary directory.

This meant these tests were all writing files to the build directory.
This is messy, though thankfully not a correctness issue or a race
because `g_mkstemp()` guarantees to return a unique file for each
caller.
