As best I can tell, guile22 is only in the installer env because
we include gdb and gdb depends on the libraries from it. gdb's
dep is for guile scripting support, AIUI. I don't think any kind
of libreport or manual gdb debugging we'd do in the installer env
would need that support, and even if it does, the ccache does
seem to be a cache - docs say if the files are not present,
they'll be generated on the fly from the .scm format sources in
/usr/share/guile/2.2. So I think it should be safe to ditch this
cache, which is large (it takes up ~38M uncompressed).
