[LTP] [PATCH v2 5/5] swapon03: Remove grep dependency

[Petr Vorel]

Hi all,

note for myself.

This change requires to normalize TMPDIR via realpath() otherwise grep will
fail. Either in the test or in the library [1] (I'll submit it separately, no
need to be part of Wei's cleanup).

Kind regards,
Petr
