Client utils: Update utils.unmap_url_cache, added hash_file

Checking hashes for files is a handy utility function for
client side tests, so moving the function hash_file to
autotest_lib.client.bin.utils, and updating the function
unmap_url_cache. Also updated the parts of the code that
reference the previously mentioned functions.
