[LTP] [PATCH] lsmod01: parse a copy of /proc/modules

[Stanislav Kholmanskikh]

In my environment, if TMPDIR is on NFSv4, this test case fails with:

lsmod01 1 TFAIL : lsmod output different from /proc/modules.
  21c21
  < sunrpc 207591 28
  ---
  > sunrpc 207591 29

To avoid such problems I separate the process of getting data from
/proc/modules and the process of parsing it in the pipe structure.

This was found while preparing for the next LTP release.
