Changed order of nfs exports parameters for FreeBSD

Fix Issue 4307: FreeBSD fix interface device names in /etc/rc.conf

https://github.com/mitchellh/vagrant/issues/4307

Fix details:
Pass network interface name to template renderer and use it
in static and dhcp templates to render /etc/rc.conf entries.

  modified:   plugins/guests/freebsd/cap/configure_networks.rb
  modified:   templates/guests/freebsd/network_dhcp.erb
  modified:   templates/guests/freebsd/network_static.erb

Verification scenario:
Check if /etc/rc.conf contains vtnet entries when paravirtualized
NIC devices are used in FreeBSD guest.
Fix network_dhcp template.

Selecting for duration of timeout can cause hang

When specifying a timeout, the subprocess used to select for timeout seconds on the stdout, stderr pipes.

This creates a race condition and can cause the `Subprocess#execute` to hang for the full timeout interval if the process has already exited and no more output is send to the pipes.

This race is happening with a higher probability if the subprocess is generating a lot of output.

Ignoring SSHKeyBadOwner if user is root (uid 0)

Scrub SSH PTY output to filter out command echo-ing.
Use -f argument to rm to force-remove files.

When using pty=true, removing files using sudo may request confirmation,
which will hang the connection.

Similarly, sometimes assumptions about file existence may be wrong and
in those cases it seems better to continue on as long as the file does
not exist, so -f makes sense there, too.
Preserve exit code while using pseudo-terminal hack.
