autotests: ask the mime database which type a test means

shared-mime-info 2.5.1 made application/x-shellscript another name of
text/x-shellscript and made text/x-csrc a kind of text/x-c++src. Tests
that spell those names out fail on the renames alone, although the files
they look at are the same as ever.
