[LTP] [PATCH v2 1/2] OVL_MNT: add setup_overlay helper

Thanks for ideas, agree with it.

Other thing is to have const char *file, const int lineno as first parameters
for mount_overlay_() and create mount_overlay() and SAFE_MOUNT_OVERLAY() as macros,
which would use it. See tst_mkfs{_,}() as examples.
