fix: restore system level properties for build integration. (quarkusi…

…o#1062)

in cleaing up properties handling we missed that jbang build integration,
especially quarkus, relied on properties being in system properties.

Fix for now is to set system properties temporariliy before jbang integration
called and then restored again.

Fixes quarkusio#1058
