buildman: don't fail --list-toolchains when toolchains fail

When a toolchain invocation fails, an exception is thrown but not caught
which then aborts the entire toolchain detection process. To solve this,
request that exceptions not be thrown, since the toolchain init code
already error-checks the command result. This solves e.g.:

         - found '/usr/bin/winegcc'
Traceback (most recent call last):
...
Exception: Error running '/usr/bin/winegcc --version'
