RFE: differentiate file and directory dependencies using a trailing '/'

RPM has only path and directory dependencies, largely because the path canonicalization in rpmCleanPath() always strips a trailing '/' character.

Luckily, the (arguably hacky) fix is not very complicated.

1. always over allocate paths by 1 byte to accomodate a trailing '/' (if necessary.

2. Copy the trailing character of the input argument to rpmCleanPath() to the return value when it's a trailing '/'

The above heuristic starts to propagate a hint to the expected file type throughout rpm, thereby diffentiating dir/file dependencies with stricter tests for, say, %ghost marked paths.
