[PULL 5/8] qga: Add support for user password setting in FreeBSD

[Konstantin Kostiuk <kkostiuk@redhat.com>]

From: Alexander Ivanov <alexander.ivanov@virtuozzo.com>

Move qmp_guest_set_user_password() from __linux__ condition to
(__linux__ || __FreeBSD__) condition. Add command and arguments
for password setting in FreeBSD.
