fix(test): improve sensitivity of hygene tests

Browse Source 
The change in 07f855d781 introduced a
trailing numeral of some kind after the `extern crate
compiler_builtins`, which appears to have caused at least two false
negatives (654b924 and 657fd24). Instead, this change normalizes the
test output to ignore the number (of symbols rustc recognizes?) to avoid
needing to re-`--bless` these two tests for unrelated changes.
