rustup: Fix for locale bug

posixphreak · posixphreak · commit c24f35389d5c · 2015-02-16T22:17:15.000+02:00
Since `tr` converts lowercase to uppercase according to system locale using `LC_CTYPE` environment variable; on some locales, rustup.sh fails to use correct variables names, thus deletes temporarily downloaded files and gives a meaningless error as shown below. This a simple fix which explictly sets `LC_CTYPE` as `C`.
