Test runs timing out on b5

Christos,

Since these commits of yours:

  2017.01.12.00.38.01 christos src/lib/libc/gen/Makefile.inc 1.197
  2017.01.12.00.38.01 christos src/lib/libc/gen/syslog.c 1.56
  2017.01.12.00.38.01 christos src/lib/libc/gen/syslog_private.h 1.1
  2017.01.12.00.38.01 christos src/lib/libc/gen/syslog_ss.c 1.1
  2017.01.12.00.38.01 christos src/lib/libc/gen/xsyslog.c 1.1

the following test cases are all timing out:

  lib/libc/gen/t_sleep:kevent
  lib/libc/ssp/t_ssp:fgets
  lib/libc/ssp/t_ssp:getcwd
  lib/libc/ssp/t_ssp:gets
  lib/libc/ssp/t_ssp:memcpy
  lib/libc/ssp/t_ssp:memmove
  lib/libc/ssp/t_ssp:memset
  lib/libc/ssp/t_ssp:raw
  lib/libc/ssp/t_ssp:read
  lib/libc/ssp/t_ssp:readlink
  lib/libc/ssp/t_ssp:snprintf
  lib/libc/ssp/t_ssp:sprintf
  lib/libc/ssp/t_ssp:stpcpy
  lib/libc/ssp/t_ssp:stpncpy
  lib/libc/ssp/t_ssp:strcat
  lib/libc/ssp/t_ssp:strcpy
  lib/libc/ssp/t_ssp:strncat
  lib/libc/ssp/t_ssp:strncpy
  lib/libc/ssp/t_ssp:vsnprintf
  lib/libc/ssp/t_ssp:vsprintf
  lib/libevent/t_event:kqueue
  lib/libevent/t_event:poll
  lib/libevent/t_event:select

Since each test case takes 600 seconds to time out, this increases the
total runtime of the tests by more than 3 hours, causing the ATF test
run as a whole to also time out.  This is affecting amd64 and sparc on
bablyon5 (i386 is not even building at the moment).
