fix(distroutils): encode cmd_input argument for ext_utils.run_send_stdin()

The method ext_utils.run_send_stdin() (in extensionutils.py) requires
the second argument, cmd_input, to be a bytes object, not a string
object. This is due to the usage of: subprocess.Popen().communicate().
Encode the password as utf-8 when passing to ext_utils.run_send_stdin().

fix(distroutils): add **kwargs to FreeBSDDistro.chpasswd()

When operating FreeBSD, the argument crypt_id is passed to an
overridden method chpasswd() in the FreeBSDDistro class. The definition
of this method does not contain an argument for 'crypt_id' or
'salt_len'. To address this issue, add **kwargs to the definition of
chpasswd() in the FreeBSDDistro class.

Commit to master (Aug 23, 3034):
This was not related to the issue, but it's inclusion is appropriate to the FreeBSDDistro class.

fix(distroutils): use /etc/pw.conf to discern accounting information.

/etc/user.defs is the shadow configuration file. FreeBSD user management
uses the pw utility.
