podman-remote build use .containerignore over .dockerignore

$ mkdir zzz;cd zzz
$ printf "FROM quay.io/libpod/testimage:20210610\nCOPY ./ ./\nCOPY subdir ./\n" >Dockerfile
$ printf "*\nsubdir\n\!*/sub1*\n" >.dockerignore
$ mkdir subdir; touch subdir/sub1.txt
$ ../bin/podman-remote build .

Should fail, but succeeds because we are not sending over the
.dockerignore file to the server side.  This PR will send the
.dockerignore so the server side and use it.

Fixes: #10907

Also if both .containerignore and .dockerignore in the context
directory, podman-remote should prefer .containerignore and not use
.dockerignore.

Fixes: #10908
