Subject: [PATCH] runtime: include os_*.h in the generated Go structs

Adding the #include to defs.c makes it get processed
by cmd/dist, which writes out Go equivalent for all the
C data structures defined in defs.c.

This in turn makes it necessary to define the Plink type,
used in os_plan9.h, in os_plan9.go. Rename it to _Plink
to avoid being exported.
