feat(xtask): add support for custom VMM and Hermit args

[mkroening]

This PR adds support for passing custom arguments to VMM and Hermit when using xtask. This allows you to set runtime environment variables via Hermit arguments, for example, which is necessary for #2416 to be useful.

Instead of

HERMIT_LOG_LEVEL_FILTER=trace cargo xtask ci rs --arch x86_64 --package rusty_demo qemu

You would now do

cargo xtask ci rs --arch x86_64 --package rusty_demo qemu -- -- env=HERMIT_LOG_LEVEL_FILTER=trace
