[PATCH 2/2] efi: payload: env: don't execute unmatched network driver glob

[Ahmad Fatoum]

When /boot/network-drivers/ doesn't exist, the glob remains unexpanded
and the script tries to execute the literal pattern, so every ifup
without a firmware provided network device printed:

  /boot/network-drivers/*: No such file or directory
  ERROR: ifup: Running '/env/network/eth0-discover' failed with 127

Skip non-existent entries.
