Fix basename handling and unit tests

See merge request !40

The basename filed in the file info returned by FileModel was incorrect
for files with the incorrect extension, flagged up by failing unit test
cases.

A number of changes have also been made so that the unit tests run
correctly and without spurious failures.

[nemo-filemanager] FileModel: use euidaccess() instead of access() to check read permissions. JB#47766

access() returns a result based on the real uid/gid rather than
the effective uid/gid. If the calling process has gid=nemo but
egid=privileged then it is still able to read the listing of a
privileged directory.
