user/scrot: Repair build, use --docdir properly

--docdir patch is from upstream:
resurrecting-open-source-projects/scrot@ee8121c65d1e

We were removing a configure line for dash compat, but since the
autotools bump we don't need to do that.  That removal was now causing
build failures.  This fixes #712.

+Subject: [PATCH] autotools: 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.
