Sometimes we wish to ensure that files or directories are not installed
somewhere that may prove detrimental to the operation of the system. For
example, this may be the case if files are placed in a directory that is
utilised as a mount point at run time, thus making them inaccessible once
when the mount point is being utilised.
Implement the prohibited paths QA test, which enables such locations to be
specified in a "IMAGE_QA_PROHIBITED_PATHS" variable. This implementation
allows for a colon separated list of paths to be provided. Shell style
wildcards can be used.
