name-hash: properly fold directory names in adjust_dirname_case()bp/name-hash-dirname-fix

Correct the pointer arithmetic in adjust_dirname_case() so that it calls
find_dir_entry() with the correct string length.  Previously passing in
"dir1/foo" would pass a length of 6 instead of the correct 4.  This resulted in
find_dir_entry() never finding the entry and so the subsequent memcpy that would
fold the name to the version with the correct case never executed.

Add a test to validate the corrected behavior with name folding of directories.
