12814	Add prereq-0.9-install to .hgignore	jdemeyer	GeorgSWeber	"To fix upgrading from versions of Sage which still have the `spkg/base` repository and which have prereq-0.9, we should add `prereq-0.9-install` to `.hgignore` in the root repository, just like we already do for `prereq-0.7-install` and `prereq-0.8-install`.

This is needed since #12112 upgraded prereq to prereq-1.0, so the root repo doesn't contain `spkg/base/prereq-0.9-install` anymore.

'''Apply''' [attachment:12814_prereq_hgignore.patch] to the SAGE_ROOT repository."	defect	closed	blocker	sage-5.0	build	fixed				N/A	John Palmieri	Jeroen Demeyer	sage-5.0.beta13
