test-image-locking leaves some temporary files around - clean
them up. While we're at it, test-image-locking is a unit test,
so it should not use "qtest.*" for temporary file names. Give
them better names instead, so that it clear where the temporary
files come from.

Perhaps we should use g_unlink() instead for better portability? although
this is pre-existing.

otherwise, lgtm

I thought about that, too, but apparently you have to include an additional 
header file (gstdio.h) to get the prototype - so it seems to be more effort 
for no real gain (unless you want to use non-ASCII characters in the 
filename - which we are not doing here).
