`update_references.sh` no longer works for subdirectory

[nikomatsakis]

The new update-references.sh script doesn't compute subdirectories correctly, I fear:

> ./update-references.sh ../../../build/x86_64-unknown-linux-gnu/test/ui/ single-use-lifetime/*rs
updating ./fn-types.stderr
updating ./one-use-in-fn-argument-in-band.stderr
updating ./one-use-in-fn-argument.stderr
updating ./one-use-in-inherent-impl-header.stderr
updating ./one-use-in-inherent-method-argument.stderr
updating ./one-use-in-inherent-method-return.stderr
updating ./one-use-in-trait-method-argument.stderr
updating ./two-uses-in-inherent-method-argument-and-return.stderr
updating ./zero-uses-in-fn.stderr
updating ./zero-uses-in-impl.stderr

Those files should have been placed in ./single-use-lifetime/xxx.stderr. Looking more closely at the bash script, the reason is fairly clear.

This patch seems to work for me, though I think it may fail if you run update-references from the wrong directory .. maybe?

Yes, apologies! I'll try to post a fix asap.
