[Buildroot] [git commit branch/2019.02.x] utils/test-pkg: fix long option parsing

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=d8583e3657f6f20d73b7c74c8c111dd7da959ef6
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.02.x

The long option parsing of test-pkg is broken because:
- some long options are not declared
- there should be a comma between long options, the colon does not replace
it.

This change also revealed that the declaration of 'toolchains-dir' should
have been 'toolchains-csv', originally introduced in commit ed59f81a3cb4ddb.
