Set the FreeBSD /etc/salt dir to PREFIX/etc/salt

The FreeBSD port version of saltstack uses /usr/local/etc/salt rather
than /etc/salt for its configuration.
Respect the environment.

Remove the check for the TEMP_CONFIG_DIR as the FreeBSD SALT_ETC_DIR is
irrespective of the TEMP_CONFIG_DIR.

Fix daemons_running() on small window installations.

Handily ps(1) output is truncated to the size of the window, this
causes the running check to fail on consoles with small windows as the
salt-{minion,master,syndic} strings will not appear properly in the
output which is passed to grep(1). The use of multiple -w passed to
ps(1) prevents the truncation of the process lines.
