android envsetup: Make passing --target-arch an error.

android envsetup: Make passing --target-arch an error.

This is to make sure I found all the bots that used to pass this. I'll
completely remove the flag in a day or two.

Also remove the function for printing usage information. I accidentally removed
processing for --help in r252034, but having a --help flag for printing --help
as only supported flag is a bit silly anyways, so get rid of this.

(Depends on https://codereview.chromium.org/170783015/

:-/

Is the "[raw]" good enough for this? (
https://codereview.chromium.org/download/issue173003003_100001.diff ) The patch
is small enough that that might work; if I reupload I lose tryjob state. (But if
you want, I can reupload too.)

Ok, patch set 5 has working side-by-side diffs. Patch set 4 has green try runs.
