file(GET_RUNTIME_DEPENDENCIES): Fix resolution of repeated ELF dependencies

Browse Source 
When a library file name is encountered multiple times, reuse the result
from the first time.  This more closely matches the behavior of the
dynamic loader on Linux.

5. Otherwise, the dependency is unresolved.

Resolution of each encountered library file name occurs at most once
while processing a given root ELF file (executable or shared object).
If a library file name is encountered again in the dependency tree,
the original resolution is assumed. This behavior more closely matches
the dynamic loader's behavior on Linux.
On Windows platforms, library resolution works as follows:
1. DLL dependency names are converted to lowercase for matching filters.
