Adhemerval Zanella 053fe27343 linux: Fix __closefrom_fallback iterates until max int (BZ#28993) 
The __closefrom_fallback tries to get a available file descriptor
if the initial open ("/proc/self/fd/", ...) fails.  It assumes the
failure would be only if procfs is not mount (ENOENT), however if
the the proc file is not accessible (due some other kernel filtering
such apparmor) it will iterate over a potentially large file set
issuing close calls.

It should only try the close fallback if open returns EMFILE,
ENFILE, or ENOMEM.

Checked on x86_64-linux-gnu.
