Use rsync to exclude copying the fsmonitor--daemon.ipc

This prevents a copy error where the system is unable to copy the ipc
file due to being a socket. This would otherwise manifest as errors
during pod install with the message "too long unix socket path" if git's
`core.fsmonitor` feature is enabled.

Resolves #11640
