[Fuego] Backport for LTS 4.4.129 for LTP fnctl35 tests

[Daniel Sangorrin]

Dear Ben,

The other day I mentioned on the list[1] that after running LTP with
Fuego there were a few test cases failing that needed investigation.

I reviewed the first one (fcntl35 and fcntl35_64). According to the
comments on the LTP fcntl35.c file (by Xiao Yang <yangx.jy at cn.fujitsu.com>)
the bug tested by this test case was fixed by:
    commit 086e774a57fba4695f14383c0818994c0b31da7c
    Author: Michael Kerrisk (man-pages) <mtk.manpages at gmail.com>
    Date:   Tue Oct 11 13:53:43 2016 -0700

I backported that patch, see next e-mail:
[PATCH] pipe: cap initial pipe capacity according to pipe-max-size

I tested again and confirmed that the patch fixed the bug.

Before:
fcntl35.c:98: FAIL: an unprivileged user init the capacity of a pipe to 65536 unexpectedly, expected 4096
After:
fcntl35.c:101: PASS: an unprivileged user init the capacity of a pipe to 4096 successfully

If you think the patch is OK (as mentor) I can send it to the LTS mailing list myself.

Thanks,
Daniel Sangorrin
