Increase timeout from the default 20s to 40s. This test makes close to
2 million syscalls with distribution:

1180249 connect
 297952 getsockname
 144040 lseek
 143734 read
  14466 close
...

connect can be slow, so the default timeout was not enough on slow
systems.

	* nss/tst-nss-files-hosts-multi.c (TIMEOUT): Define.

OK for master.

Here it's plausible that this test does timeout, but 40s is fine
for normal testing.

Thank you for these patches, Szabolcs.  I experience more tests always
failing due to timeouts on one machine.  Unfortunately, they are different
tests than those which you have fixed.  But I will take your work as an
example and investigate what timeout values should be to satisfy tests
on this particular machine.

The tests currently failing for me due to timeouts are:

FAIL: nptl/tst-robust-fork
FAIL: nss/tst-nss-files-hosts-getent
FAIL: stdlib/test-bz22786
FAIL: timezone/tst-tzset

Regards,

Rafal
