Bug
1557788 - Remove NEED_XVFB from Linux instrumented and rusttest builds; r=firefox-build-system-reviewers,chmanchester
xvfb was used to create a virtual framebuffer for running Firefox during
build jobs to support PGO profile generation. That now runs in a
separate task, so we don't need this flag for builds anymore.
Note that other Linux builds still need xvfb in order to run xpcshell in
'make check'.
