gnu: podman: Revamp the package.

Substantial rework of the podman package.  The source is no longer patched (at
all) and all necessary modifications were moved into wrap-program and phases.

Not everything is supported out of the box, but description mentions what
packages to install to get additional functionality working.

* gnu/packages/containers.scm (podman)[source]: Remove snippet and patches.
[arguments]<#:make-flags>: Add HELPER_BINARIES_DIR.  Add GOMD2MAN to actually
use go-github-com-go-md2man package instead of the bundled version.
<#:imported-modules>: Add (guix build go-build-system).
<#:phases>{'set-env}: Set `CC' as an environment variable due to bug in make
before 4.4.
{'fix-hardcoded-paths}: Remove everything except patching `libexec' and `lib'
locations.
{'symlink-helpers}: New phase symlinking tools not discoverable via $PATH into
one directory (`HELPER_BINARIES_DIR').
{'wrap-podman}: New phase wrapping `podman' to set correct $PATH.
{'remove-go-references}: New phase stripping references to the golang
toolchain from the binaries.
[inputs]: Remove no longer needed cni-plugins, slirp4netns.  Remove referenced
in 'wrap-podman conmon, crun, iptables, passt.  Move go-github-com-go-md2man
into native-inputs.  Add bash-minimal.
[native-inputs]: Add custom grep with supported -P.  Use newer go.  Add
mandoc.
[description]: Explain how to get `podman compose' and `podman machine'
working.
* gnu/packages/patches/podman-program-lookup.patch: Delete file.

-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.
