container: workdir resolution must consider symlink if explicitly configured
While resolving `workdir` we mostly create a `workdir` when `stat`
fails with `ENOENT` or `ErrNotExist` however following cases are not
true when user explicitly specifies a `workdir` while `running` using
`--workdir` which tells `podman` to only use workdir if its exists on
the container. Following configuration is implicity set with other
`run` mechanism like `podman play kube`

Problem with explicit `--workdir` or similar implicit config in `podman play
kube` is that currently podman ignores the fact that workdir can also be
a `symlink` and actual `link` could be valid.

Hence following commit ensures that in such scenarios when a `workdir`
is not found and we cannot create a `workdir` podman must perform a
check to ensure that if `workdir` is a `symlink` and `link` is resolved
successfully and resolved link is present on the container then we
return as it is.

Docker performs a similar behviour.
