Austin Clements 88f89d87c4 cmd/cgo/internal/test: fix TestThreadLock
This test was introduced in CL 18882, but only recently enabled as of
CL 493603. It's intended to check that we don't move executing C code
between threads when it re-enters Go, but it has always contained a
flake. Go *can* preempt between the Go call to gettid and the C call
to gettid and move the goroutine to another thread because there's no
C code on the stack during the Go call to gettid. This will cause the
test to fail.

Fix this by making both gettid calls in C, with a re-entry to Go
between them.

Fixes #60265
