commit 07baa71eda8d1047f003acc7ea32ad6b6600b179 upstream.
Break out the code to create the string and writing it to the file
descriptor from log_ref_write and into a dedicated function log_ref_write_fd.
For now this is only used from log_ref_write but later on we will call
this function from reflog transactions too which means that we will end
up with only a single place where we write a reflog entry to a file instead
of the current two places (log_ref_write and builtin/reflog.c).
