MFC r335641:

Fix a stack overflow in mount_smbfs when hostname is too long.

The local hostname was blindly copied into the to the nn_name array.
When the hostname exceeded 16 bytes, it would overflow.  Truncate the
hostname to 15 bytes plus a 0 terminator which is the "workstation name"
suffix.

Use defensive strlcpy() when filling nn_name in all cases.
