hush_test: filter test output to avoid C lib differences
...
The getopt function in some C libraries wraps the option in single quotes
while others do not. Avoid the issue by running sed on the output and
strip all quotes.

hush: implement type
...
Implement support for the POSIX `type` command. Only POSIX stuff is
supported here, no bash extensions like -p or -P.
In the process, split the $PATH searching code out of builtin_source() and
into its own find_in_path() function so we don't duplicate it.
