Removing the need for rm -rf

[edrozenberg]

The script worked well to get rid of the Tahoe garbage update harassment, thanks! Absolutely despise Anal Dye's Liquid Ass.

A small idea to remove the need for rm -rf in case the mktemp ever somehow returns a / :) -

rm -f "$TEMP_PROFILE"
rm -f "TEMP_DIR"

(I assume the profile file is the only thing that would be in that temp dir)

Optionally TEMP_DIR could also be validated as containing a /var/folders string.

@edrozenberg - can you make a PR for this? Would make it easier to add.
