Add httpd fix to watcher api containerfile

When trying to run a Watcher API container built with the existing
container file, the httpd server fails with the error
"SSLCertificateFile: file '/etc/pki/tls/certs/localhost.crt'
does not exist or is empty". We already have an script to fix it [1],
but it's not used for the watcher api image, this change adds it.
