toolchain-shar-extract.sh: Handle special characters in script path
Extracting SDK archive may fail if the script is run using a path with
special characters such as space or asterisk. This is because the shell
interprets such characters after expanding the $0 variable.
Added quotes to all uses of the shell variable $0 to fix this.
