Subject: [PATCH] go.toolchain{,.next}.rev: bump Go 1.27 to pick up mips64
 stkobj alignment fix

The previous tailscale.go1.27 build (based on go1.27rc2) crashed all
linux/mips64 and mips64le binaries with SIGBUS under qemu-user, which
made tstest/archtest fail in CI: the compiler under-aligned the
.stkobj funcdata records that the runtime reads as uintptrs
(golang/go#80668). The new build carries the fix. Verified locally
that tstest/archtest passes for mips64 and mips64le under qemu.

Updates #20220
