astraceroute: Fix for reading mirrors from file

If the file that GeoIP mirror addresses are being read from lacks a
terminating newline, then the code that reads them in exhibits an
off-by-one error.

Example of such a file:

   $ xxd /etc/netsniff-ng/geoip.conf
   00000000: 6765 6f6c 6974 652e 6d61 786d 696e 642e  geolite.maxmind.
   00000010: 636f 6d                                  com

Fix this by explicitly getting the part of the string before the
newline using `strcspn`.
