Make chrome://memory-redirect visible on Android.

In c/b/browser_resources.grd, value of |is_posix| turned to
be false on Android, so Android Chrome did not show HTML for
chrome://memory-redirect.

I changed the branch condition to show one of
about_memory{,_mac,_linux}.html depending on its platform.

BUG=337543
TEST=open chrome://memory

[NaCl SDK] Add fake for ppb_host_resolver and ppb_net_address

Also add tests for gethostbyname that usese these fakes
and fix the resulting leaks found in host_resolver.cc.

Also add a third variant of ki_init() which takes a
PepperInterface instance. This can be used by the test
code to inject a fake pepper interface.
