OBR script changes

[Tom-Slattery]

The OBR script seems to set the value of GALASA_BUILD_TOOL_PATH using the get_galasabld_binary_location method, then overwrite that value for each method that uses galasabld. This causes the script to fail for me when galasabld is on my path. I've removed the extra setting of GALASA_BUILD_TOOL_PATH and used the value obtained by get_galasabld_binary_location.

For each mvn call I've added:
--settings ${WORKSPACE_DIR}/obr/settings.xml
-Dgpg.skip=true \

So that maven uses the settings.xml file in the workspace, allowing the value of galasa.source.repo and galasa.central.repo to be use (otherwise this fails for me).

I've also skipped gpg signing here as the maven calls seem to only pull from remote Maven and build to local Maven - signing didn't seem necessary here.

Addressed the GPG Passphrase with the new commit. Also wanted to mention that I've added extensions to the dependency download step as that wasn't in my original comment:
