Introduce blacklist_interp to allow ignoring of interpreted files

[wolfgangkarall]

My use case: running needrestart via ansible shows sometimes false positives for /tmp/ansible_* files, finding parent sshd -> wants to restart ssh.service more often than necessary.

Just an example output of such a case, it's no triggered every time:

$ ansible news3 -sa 'needrestart -v'
