tests/meson.build: Turn file list into list of file objects

When a file object is created, Meson also checks if the file actually
exists and an error points to the specific line of meson.build if not.
If just a list of filenames is used, then the error occurs at the line
where the list is used.

Thus, use file objects in tests/meson.build for more useful error
messages.
