Log:
[ruby/rubygems] Don't mask install errors when no Gemfile can be located

require_tree_for_spec calls SharedHelpers.default_gemfile to build the
"In Gemfile:" header of the error report. When BUNDLE_GEMFILE is unset
and no Gemfile is findable from the current directory, that raises
GemfileNotFound from inside the error-reporting path, hiding the
original install errors behind "Could not locate Gemfile". Fall back to
a generic header so the real errors always surface.
