Support -uUser and -pPassword without additional space

Copied from Debian bugtracker https://bugs.debian.org/760164:

Torsocks doesn't recognize the arguments to the -u (--user) and -p (--pass) options if they immediately follow the option characters:

$ torsocks -uMyUser -pMyPass /bin/true
/usr/bin/torsocks: 226: command: Illegal option -u
ERROR: -uMyUser cannot be found.
/usr/bin/torsocks: 261: exec: -uMyUser: not found

It works if you put a space between the option and the argument:

$ torsocks -u MyUser -p MyPass /bin/true

Torsocks should support the former syntax too, as it is standard on UNIX-like systems.

This is not going to be a priority unless someone thinks it's worthwhile enough to drop a patch.
