buildah bud is gobbling stdin

[edsantiago]

buildah bud is gobbling stdin that does not belong to it. This makes it impossible to pipe script commands to a shell.

$ printf "echo hi\r\nbuildah bud -t foo .\necho bye\n" | bash
hi
STEP 1: ...
...
<sha>

Note that the 'echo bye' is gobbled up by buildah. If you redirect stdin on the buildah command, it works as expected:

$ printf "echo hi\r\nbuildah bud -t foo . </dev/null\necho bye\n" | bash
hi
...
bye

I am not seeing this happen on the main branch of Podman, BTW. But opened a PR anyways,

This is fixed in master branch.
