DAOS-16406 test: file_count_test_base.py - Don't obtain dfuse mount_d…

…ir from test yaml (#14993) (#15023)

Remove the following from file_count_test_base.py
mount_dir = self.params.get("mount_dir", "/run/dfuse/*")

dfuse mount_dir used to be defined in the test yaml, but now the harness creates a
unique directory per test. mount_dir definitions were removed from the test yaml
in PR11453.

Affected tests are:
deployment/io_sys_admin.py
io/large_file_count.py
io/small_file_count.py
