Apparently `$LOAD_PATH.resolve_feature_path('erb/escape')` returns true
for miniruby but `require 'erb/escape'` fails on it.
I still don't want to check it and rescue LoadError at the same time
because the code looks too complicated. Let me just rescue LoadError for
platforms that don't build native extensions.
