[LTP] [PATCH v2 1/4] lib/tst_path_has_mnt_flags.c: Factor out tst_path_has_mnt_flags() for new API

[Xiao Yang <yangx.jy@cn.fujitsu.com>]

We can use existed tst_path_has_mnt_flags() to check whether a path is
on a filesystem that is mounted with specified flags, so ensure that the
function can also be used by new API.
