runtime: use named macros on NetBSD 

It will use the full names that appear in netbsd's /usr/include/sys/syscall.h names.
This adds some compat-goo (sys_sigprocmask->SYS_sigprocmask14), which might not be pretty, but the information about whether the compat version is used is probably important, as Go will keep using interfaces even after they are considered compatibility, which has caused problems in the past.
also, the same names appear in ktrace (with the numbers).
