Read ldcache at construction instead of on each locate call
This change udpates the ldcache locator to read the ldcache at construction
and use these contents to perform future lookups against. Each of the cache
entries are resolved and lookups return the resolved target.

Assuming a symlink chain: libcuda.so -> libcuda.so.1 -> libcuda.so.VERSION, this
means that libcuda.so.VERION will be returned for any of the following inputs:
libcuda.so, libcuda.so.1, libcudal.so.*.
