test: make test-fs-access stricter

Change regular expression matching in `assert.throws()` to match the
entire error message. In `assert.throws()` that uses a function for
matching rather than a regular expression, add checks for the `message`
property and the error's constructor.

Also, refactored to remove unnecessary temp file handling. No need to
remove temp files after the test. Each test is responsible for clearing
the temp directory if it needs to use it.
