Auto merge of #10072 - russweas:master, r=alexcrichton

Implement escaping to allow clean -p to delete all files when directory contains glob characters

Closes #10068.

Runs `glob::Pattern::escape` on path input to `rm_rf_glob()`. This fixes a bug in which `cargo clean -p` fails to delete a number of files from `target/` if the path to target contains glob characters.
