syscall.Faccessat and os.LookPath regression in Go 1.20 [1.20 backport]

@kolyshkin requested issue #58552 to be considered for backport to the next 1.20 minor release.

@gopherbot Please backport to Go 1.20.

Change https://go.dev/cl/469956 mentions this issue: [release-branch.go1.20] syscall: Faccessat: check for CAP_DAC_OVERRIDE on Linux

[kolyshkin]

Please consider this backport -- it is a serious regression in Go 1.20, preventing a binary from being executed in a certain scenario (see details in the original issue).
