cnd up fails if there are symlinks in the source folder

[rberrelleza]

Describe the bug
running cnd up con a folder where there are symlinks fails with the error below. It seems like the archiver library we are using to tar doesn't work well with symlinks.

DEBU[0004] cnd-sync init cointainer is now running, sending the tarball
ERRO[0008] failed to tar source folder: walking /Users/ramiro/go/src/bitbucket.org/okteto/cli: /Users/ramiro/go/src/bitbucket.org/okteto/cli/vendor/github.com/docker/docker/integration-cli/fixtures/https/ca.pem: opening: open /Users/ramiro/go/src/bitbucket.org/okteto/cli/vendor/github.com/docker/docker/integration-cli/fixtures/https/ca.pem: no such file or directory

Desktop (please complete the following information):

• macOS
