libgo: additional type/const references in sysinfo.c

Add a few more explicit references to enumeration constants
(RUSAGE_SELF, DT_UNKNOWN) in sysinfo.c to insure that their hosting enums
are emitted into DWARF, when using a clang host compiler during
the gollvm build.

Updates golang/go#41382.
Updates golang/go#41404.
