libdaq3,snort3: install/use libdaq3 in its own dir
If used with default paths, libdaq 2.x and libdaq 3.x will overwrite
some of the other version's files. Install them in different places to
avoid trouble.
Snort is the only package that uses libdaq, so update it at the same
time to avoid creating a failing commit.
