Josh Rickmar 661d749b94 unix: use libc stubs for OpenBSD pledge+unveil 
Future OpenBSD releases will remove the syscall(2) interface.
This converts the Pledge and Unveil calls to use pledge(2) and
unveil(2) from libc, rather than indirectly through syscall(2).

Updates golang/go#63900.

Josh Rickmar 249e16f7ca unix: require minimum OpenBSD 6.4 for pledge, unveil 
OpenBSD 7.3 and 7.4 are the only supported OpenBSD releases.  This change simplifies the version detection and error handling to require at least OpenBSD 6.4 to call the Pledge and Unveil functions.

Updates golang/go#63569.

Josh Rickmar 304f187cdb unix: replace use of strcpy in mkerrors.sh 
On OpenBSD-current, clang emits a warning message to standard output for the use of strcpy, e.g.:

_errors.c(/tmp/_errors-673190.o:(main)): warning: strcpy() is almost always misused, please use strlcpy()

This message makes it into the Go source being created, causing gofmt to error on the invalid syntax, and leaving the zerrors file empty.

Using strlcpy would be preferred here, but strncpy is enough to silence this message, and is more portable.
