system_dlsym() takes a uuid in one of the memref parameters. Prior to
this patch that memref wasn't checked correctly in all cases.
system_dlsym() passes the uuid to ldelf_dlsym() which uses this uuid so
the pointer must be valid and of the expected size. Fix this by checking
that the pointer is non-NULL and of the correct size.
This fixes coverity scan:
CID 1501812 (#1 of 1): Dereference after null check (FORWARD_NULL)
Fixes: ebef121c1f5c ("core, ldelf: add support for runtime loading of shared libraries")
