fix: legalhold test to work properly

The awscli tests for virtual style paths (dnsmasq fix) (#278)

- Add new mode to test virtual host style with awscli

Mint awscli tests now run against both path style and virtual style
if virtual style flag is set. By default only path style tests are
run

- The dnsmasq will now resolvethe wildcard entries also

This will now facilitate the randomized wildcard bucket names
in awscli tests (virtual style paths).

Fixes #213
