Review Request: 8003693: build-infra: bridgeBuild should allow for partial build (no hotspot)

[Erik Joelsson]

Making it possible to use --with-import-hotspot through bridgeBuild and 
jprt. Also converted check for open only to use same wildcard 
construction as the new HOTSPOT_AVAILABLE to avoid unneeded shell 
expressions.
