Subject: [PATCH 1/2] build: respect docdir

Before this patch with --docdir=/usr/share/doc/scrot-1.7-r1 (example downstream
versioning for patches):
```
>>> /usr/share/doc/scrot-1.7-r1/
>>> /usr/share/doc/scrot-1.7-r1/README.md.bz2
>>> /usr/share/doc/scrot-1.7-r1/ChangeLog.bz2
>>> /usr/share/doc/scrot-1.7-r1/AUTHORS.bz2
>>> /usr/share/doc/scrot/
>>> /usr/share/doc/scrot/scrot.png
>>> /usr/share/doc/scrot/README.md.bz2
>>> /usr/share/doc/scrot/ChangeLog.bz2
>>> /usr/share/doc/scrot/AUTHORS.bz2
```

After:
```
>>> /usr/share/doc/scrot-1.7-r1/scrot.png
>>> /usr/share/doc/scrot-1.7-r1/README.md.bz2
>>> /usr/share/doc/scrot-1.7-r1/ChangeLog.bz2
>>> /usr/share/doc/scrot-1.7-r1/AUTHORS.bz2
```

This avoids installing duplicate files & installs them to the
same location but it's overridable by --docdir in ./configure which
helps downstreams.
