Avoid "find /..." without excludes

[hpreusse]

Anywhere in the code the diag script calls find like this

for i in $(find / -name php.ini 2>/dev/null)

Doing find /.... without any excludes is IMHO a bad idea, as we have a huge NFS share. Consider to use locate(1) in this situation and fall back to find(1) only if there is no locate(1) or it does not return results.
