Motivation for this change

The dirb package does not provide the wordlist files which are normally available in /usr/share/dirb/wordlists . In addition the software uses hardcoded /usr/share/dirb/wordlists/common.txt. This PR fixes both issues by installing the wordlists into the package share directory and patching the hardcoded path in src/dirb.c
