An update that has two fixes can now be installed.

## Description:

This update for go1.27 fixes the following issues:

  * go1.27.1 (released 2026-09-01) includes fixes to cgo, the compiler, the
    runtime, the go fix command, and the database/sql, debug/elf, encoding/json,
    net/http, os, simd, and simd/archsimd packages. (bsc#1272545)

  * cmd/compile: malformed linker symbol for generic method with a receiver that
    is an alias to a pointer

  * database/sql: closingMutex lost wakeup deadlocks Rows.Next against
    concurrent Rows.Close
  * debug/elf: applyRelocationsPPC was broken by CL 705075
  * simd/archsimd/internal/simd_test: SIGILL on RK3588 and possibly other arm64
    processors
  * cmd/compile: GOEXPERIMENT=simd stub method parameter enforced inconsistently
    Int16s.ShiftAllLeft rejects both uint8 and uint64 arguments depending on
    context
  * cmd/fix, x/tools/go/analysis/passes/modernize: embedlit: comma in a comment
    produces invalid code
  * cmd/compile: SIGILL due to new dependency on z14 s390x instruction set
    version on z13 and earlier CPUs
  * encoding/json: quoted null rejected for string fields with the ,string
    option in Go 1.27
  * cmd/fix, x/tools/go/analysis/passes/modernize: embedlit: moving field
    assignments produces duplicate field name in struct literal
  * net/http: Request.Body.Close returns io.EOF when a handler leaves part of
    the body unread
  * database/sql: support for uuid.UUID undocumented
  * encoding/json/v2: missing io.ErrUnexpectedEOF from v1 Decoder.Token
  * encoding/json/v2: definition of "JSON-representable fields" looks incorrect
  * cmd/go: go fix embedded literal produces non-compiling program
  * cmd/compile: malformed relocation target for generic method when type
    argument name contains the method name
  * crypto/tls: client handshake tests hardcode TLSv1.0

  * fix esbuild reproducible builds (bsc#1234374)
