Use the $PATH from the runtime config, if it includes one, so that when
the command to run isn't an absolute path and the command isn't being
processed by the shell, exec.Command()'s internal call to
exec.LookPath() will find it.

Add a dummy "runtime" that just dumps its runtime config, either the
entirety of it, or a section of it corresponding to each command line
argument. Tests can use it to ensure that we set the right thing in the
configuration without also depending on the runtime to do as its asked,
which isn't always something we have control over.

Unless --no-pivot or the equivalent API flag is set, try to pivot_root()
to enter the rootfs during Run(). Fall back to using chroot() as before
if that fails for any reason.

This change is generated by `go1.23rc2 fix ./...`.
Had to use go1.23rc2, since all released go versions have a bug
preventing it from working with `go 1.22.0` in go.mod (opened
https://github.com/golang/go/issues/68825,
https://github.com/golang/go/issues/68824 for awareness).

to read files from root's home directory, where the permissions error is
treated as a hard failure.

In golang 1.19, `io/ioutil` is fully deprecated preventing Buildah from
compiling. Replace all calls with equivalent calls from the `os`
package.

Podman adds an Error: to every error message. So starting an error
message with "error" ends up being reported to the user as
Error: error ...
This patch removes the stutter.
Also ioutil.ReadFile errors report the Path, so wrapping the err message
with the path causes a stutter.

This adds no-op stubs for various things and adds an optional override
for creating the container chroot - on FreeBSD we use a jail to allow
setting the container hostname.

This intentionally breaks the FreeBSD so that I can move the code
unmodified which will help with future merge conflicts. A subsequent
commit will resolve this by factoring out Linux-specific code.

This leaves runUsingChrootSubprocOptions in the platform-specific file
since syscall.SysProcIDMap isn't available on FreeBSD.
