[PATCH] Fix some failing tests in BSD systems

[Daniel Martín]

A couple of tests are failing for me on master and a BSD system (macOS):

2 unexpected results:
   FAILED  xref--xref-file-name-display-is-abs
   FAILED  xref--xref-file-name-display-is-relative-to-project-root

An extract of a test failure is

(list-elt 0 (arrays-of-different-length 25 24
"xref-resources//file1.txt" "xref-resources/file1.txt" first-mismatch-at
15))

The reason for the failure is that BSD 'find' sometimes outputs paths
with an extra '/', for example:

find /path/emacs/test/lisp/progmodes/xref-resources/ -type f \( -iname \* \)
/path/emacs/test/lisp/progmodes/xref-resources//file2.txt
/path/emacs/test/lisp/progmodes/xref-resources//file1.txt

(Note the trailing '/' in the first argument to 'find'.)

As I think this differs from GNU find but it's still a valid POSIX path,
I decided to make the tests more flexible.

Could you install the attached patch if you think it does TRT?

Thanks.
