[LTP] [PATCH 2/2] tst_fs_setup.c: Add tst_ prefix to new API functions

[Petr Vorel]

To fix our warning due not following our policy:
tst_fs_setup.c:14:6: warning: LTP-003: Symbol 'create_overlay_dirs' is a public library function, but is missing the 'tst_' prefix
tst_fs_setup.c:27:5: warning: LTP-003: Symbol 'mount_overlay' is a public library function, but is missing the 'tst_' prefix

+ Fix missing blank line.
