Capistrano: fix up installed gem permissions after deployment.
This fixes permissions in the shared/bundle/ directory after deployment, to make it writeable by all deployers. We already set group permissions correctly in the bundle directory, but some gem installs ignore these permissions, so we need to fix them up. (I think they build files in $TMPDIR, and then move them across with the wrong group / user.) This is not immediately obvious as a problem, but sometimes makes it impossible for a single deployer to remove the installed gems for old ruby versions.
