grep: add proper support for pattern_list
From POSIX.1-2008:
The pattern_list's value shall consist of one or more patterns
separated by <newline> characters;
As such, given patterns need to be split at newline characters. Without
doing so, busybox grep will interpret the newline as part of the pattern
which is not in accordance with POSIX.
