[Libguestfs] [PATCH] fish: Do not emit error message if history file cannot be open for writing.

[Hilko Bengen]

The error message generated by perror() is not particularly useful to
the user. Many other command line programs that can keep history
around cope silently if they can't create or write to their history
file.
