[LTP] [PATCH] unshare03: use sizeof(long long) to fix for 32bit

[Avinesh Kumar]

when executing on 32bit compat layer
"nr_open = sizeof(long) * 8" does not evaluate to a large enough value
for /proc/sys/fs/nr_open.
unshare03.c:38: TBROK: Failed to close FILE '/proc/sys/fs/nr_open': EINVAL (22)
Use (long long) instead.

Fixes: fc8be6ed4 ("unshare03: Simplify EMFILE test by using fixed fd limit (sizeof(long) * 8)")
