runtime/cgo: Add initial NetBSD Thread Sanitizer support

Browse Source 
Recognize NetBSD in:
 - go/internal/work/init.go
 - race.bash
 - runtime/race/race.go

Add __ps_strings symbol in runtime/cgo/netbsd.go as this is
used internally in the TSan library for NetBSD and used for
ReExec().

Tested on NetBSD/amd64 v. 8.99.12.

Around 98% tests are passing for the ./race.bash target.

Updates #19273
