[PATCH] term/serial: Use grub_strncpy instead of grub_snprintf when only copying string

[Glenn Washburn <development@efficientek.com>]

Using grub_strncpy() instead of grub_snprintf() is less overhead and
indicates clearly that the dest should be the same string as the source.

Also fix indentation.
