bitbake: cache: Handle spaces and colons in directory names for file-checksums

If there is a space in a directory name containing a file in file-checksums
(e.g. from a file:// url), you currently get tracebacks from bitbake. This
improves the code to handle colons and spaces in the file-checksums names
since it possible to figure out the correct names.
