unix/linux: update to Linux kernel 5.19-rc2

Update to 5.19-rc2 instead of 5.18 for the following reasons:

- Support for LoongArch has been merged upstream. This allows to drop
  the loong64 specific kernel patches.
- Fixes [1] an issue encountered with when generating the
  SOCK_TXREHASH_DEFAULT constant from linux/socket.h on 5.18
- Contains a fix [2] to provide SYS_MEMFD_SECRET on linux/riscv64 as
  well, The underlying syscall was already available in earlier kernel
  versions. Also see golang/go#51547.
