[release-branch.go1.22] runtime: x_cgo_getstackbound: initialize pthread attr
In glibc versions older than 2.32 (before commit
4721f95058),
pthread_getattr_np does not always initialize the `attr` argument,
and when it fails, it results in a NULL pointer dereference in
pthread_attr_destroy down the road.
This is the simplest way to avoid this, and an alternative to CL 585019.
Fixes #67650.
