Explicitly load libcoreclrpal in corerun
Explicitly load libcoreclrpal in corerun

libcoreclr has a dependency on libcoreclrpal, but libcoreclrpal is
usually not on the path the loader probes, since it is SxS with the
runtime itself.

Instead of forcing LD_LIBRARY_PATH to be set just have corerun load the
PAL from the same folder as the runtime before loading libcoreclr.

Fixes #709
