Subject: [PATCH] Modify search for binaries to fit Guix model
Podman basically looked into the $PATH and into its libexec. That does not fit
Guix's model very well, to an additional option to specify additional
directories during compilation was added.
* pkg/rootless/rootless_linux.go
(tryMappingTool): Also check /run/setuid-programs.
* vendor/github.com/containers/common/pkg/config/config.go
(extraGuixDir): New function.
(FindHelperBinary): Use it.
* vendor/github.com/containers/storage/pkg/unshare/unshare_linux.go
(guixLookupSetuidPath): New function.
(Start): Use it.
