for-group gives write permission to all built software in the end

Since the `install' script also sets permissions manually, the permissions
that we define in `for-group' don't usually affect the installed
files. Therefore the installed files of one user can't be modified/deleted
by another. With this commit, after for-group finishes configuration, it
also adds the write flag for all group members in the whole installation
directory.

+# Group writing permissions for dependencies directory

+# The common build process sets the writing permissions of the installed
+# programs/libraries to `755'. So group members can't write over a
+# file. This creates problems when another group member wants to update the
+# software for example. We thus need to manually add the group writing flag
+# to all installed software files.
