Turn off errexit option when detecting the apg command

Commit https://github.com/shadowsocks/shadowsocks-libev/commit/f32ac38c2f7aab09ec25131209954957518de42a
allows to use pwgen to generate the initial password at the first
installation. However it won't work when apg isn't installed because:

* the postinst script has errexit option set ("set -e")
* at the first installation of ss-libev, apg or pwgen will be called to
  generate the initial password in config.json
* when apg isn't installed, "pathfind apg" would return 1
* and the postinst script will immediately exit due to "set -e"

This commit temporarily turn off the errexit option for pathfind()
