Re-land "Flip 'Linux x64' bot on chromium waterfall to GN."

This re-lands #360510 w/ a build fix to  //mojo/shell:apptests
after #360604; It looks like this was broken when we changed
//mojo/shell/application_manager.mojo in #360604 but
for whatever reason //mojo didn't include //mojo/shell:apptests.

With this fix, 'ninja all' should work again in a GN Linux x64 build.
