Android: fix resource_sizes.py strings normalization.

When normalizing for the size of untranslated strings in
resources.arsc, the number of locale .pak files was used as the number
of supported locales. This is inaccurate in Monochrome as most strings
will only be available in the 44 Chrome supported locales.

This value is now hard-coded in resource_sizes.py.
