podman: Cannot run script from mounted volume

Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind bug

Description

Running a script that resides on a mounted vokume fails

Steps to reproduce the issue:

cat > ./example <<EOF
#!/bin/bash
echo hello
EOF

chmod +x ./example

podman run -v "$PWD:$PWD" -w "$PWD" fedora:30 ./example
podman run -v "$PWD:$PWD" -w "$PWD" fedora:30 "$PWD"/example

Describe the results you received:

Error: executable file not found in $PATH: No such file or directory: OCI runtime command not found error
/bin/bash: /home/avi/example: Permission denied

Describe the results you expected:

hello
hello

Additional information you deem important (e.g. issue happens only occasionally):

Looks like there are two bugs: first, relative paths don’t work, and second, permission is denied when running a script from a mounted volume.
