test: fs_helper: Allow passing the image filename

Browse Source 
The mk_fs() function always generates its own image filename from the
prefix and fs_type. Some callers need to specify a custom leaf name
while still keeping the image under the persistent-data directory.

Add an fs_img parameter that accepts a leaf filename. When provided,
it is joined with persistent_data_dir instead of the default name.
