hostnamed: allow more special characters in pretty hostname
this addresses the bug at:
https://bugs.freedesktop.org/show_bug.cgi?id=59311
https://bugzilla.redhat.com/show_bug.cgi?id=895299
hostnamectl is supposed to allow a range of special characters for
the 'pretty' hostname:
$ hostnamectl set-hostname --pretty "Nathaniels Desktop !@#$%"
..however, it rejects apostrophes, double quotes, and backslashes.
The manual for hostnamectl suggests that this should be allowed.
It makes sense to reject \0, \n, etc. pretty_string_is_safe() is
the same as string_is_safe(), but allows more special characters.
