Bug#985384: pcp: Need to write permission to /var/log/pcp/pmfind/

[YABUKI Yukiharu]

Package: pcp
Version: 5.2.6-1
Severity: normal

Dear Maintainer,

Your pcp package need to give write permissions to /var/log/pcp/pmfind/
pcp claims that it could not touch /var/log/pcp/pmfind/pmfind_check.log.

```
root@Odayla:/home/yabuki# LANG=C ls -la /var/log/pcp/pmfind/
total 0
drwxr-xr-x 1 root root  0 Dec 18 06:11 .
drwxrwxr-x 1 pcp  pcp  98 Feb  4 03:25 ..
```


I realized that pcp user got a lot of mails like that:

```
