crendential-store: use timeout when locking file
When holding the lock for rewriting the credential file, use a timeout
to avoid race conditions when the credentials file needs to be updated
in parallel.
An example would be doing `fetch --all` on a repository with several
remotes that need credentials, using parallel fetching.
The timeout can be configured using "credentialStore.lockTimeoutMS",
defaulting to 1 second.
