android envsetup: Stop honoring CHROME_ANDROID_WEBVIEW_ENABLE_DMPROF.

Nothing sets this env var. (I checked with the folks who added this line, who
confirmed that this is unused.)

If something like this gets added again in the future, it shouldn't use a global
env var to turn it on but a single gyp define (that's hopefully identical for
desktop and mobile).
