The FreeBSD syscall convention uses the carry flag to indicate whether an error has occured. The sys_umtx_op, thr_new, and pipe2 syscall wrappers were failing to account for this convention and silently suppressing errors as a result. This commit corrects these wrappers by copying the pattern used by the other fallible syscall wrappers. Note that futexsleep1 must now explicitly ignore the ETIMEDOUT error from sys_umtx_op. Previously ETIMEDOUT was implicitly ignored because sys_umtx_op never returned an error. Fixes #43106.
