Volume mount of '.' uses internal directory

[computator]

/kind bug

When using . as the source of a volume mount podman seems to use a podman related directory for the mount instead of either using the current directory or throwing an error.

Steps to reproduce the issue:

$ podman run --rm -v .:/test -it alpine
/ # ls -la /test/
total 36
drwx------    4 root     root          4096 Jul  6 10:18 .
drwxr-xr-x    1 root     root          4096 Jul  6 10:18 ..
drwxr-xr-x    2 root     root          4096 Jul  6 10:18 artifacts
srwx------    1 root     root             0 Jul  6 10:18 attach
-rw-r--r--    1 root     root         20428 Jul  6 10:18 config.json
prw-r--r--    1 root     root             0 Jul  6 10:18 ctl
-rw-------    1 root     root           735 Jul  6 10:18 ctr.log
drwxrwxrwt    2 root     root            40 Jul  6 10:18 shm
/ #

Hmm. Probably due to it being runc that uses the paths - I'm pretty sure it runs in that directory so it can easily find the OCI spec. Easy solution is to convert relative paths to absolute as early as we can, so we get Podman's current directory.
