llmnrd: compare full hostname in query, fix off-by-one error

When checking whether the hostname matches, llmnrd does not consider the
last character of the hostnames, leading to the following incorrect
behavior:

$ ./llmnrd -H foobar
Starting llmnrd on port 5355, hostname foobar
...

$ ./llmnr-query foobaZ
LLMNR query: foobaZ IN ANY
LLMNR response: foobar IN A 10.42.0.42 (TTL 30)

Fix it by considering the full hostname. Also do only convert alphabetic
characters to lowercase using tolower(3), since its behavior is
undefined for any other characters.

Fixes #21
