android envsetup: Stop setting OBJCOPY.

I couldn't find anything that still calls this. I looked for OBJCOPY in
internal repos, and for \$OBJCOPY, ['\"]OBJCOPY, and [[{]OBJCOPY in
cs.chromium.org.

Cleanup browser blacklist code


This change also involves some cleanup of how the blacklist is defined in the code.
This will make it easier to add new dll names at compile time.

The module name check is now also case-insensitive.
