Silence grep error during build.

Ever since upgrading to Debian 7.0, building linuxptp results in an
annoying error message. This is due to the fact that the directory
/usr/include/bits is no longer present, but our makefile expects it
to exist. This patch fixes the issue by telling grep not to complain
about missing files.

trivial: break the very long lines of the get_ functions.

The get_ranged_ and get_arg_ declarations and definitions are just a wee
bit much too long. This patch breaks the overly long lines into two.
