[Libguestfs] [PATCH 1/7] fish: Do not emit error message if history file cannot be open for writing.

I noticed this error message because sbuild built the package with HOME
set to a non-existing directory which caused a test script to fail.

Not being able to save history isn't really a critical error, as far as
I'm concerned.

I have tried some other programs how they handle this situation (bash,
sqlite3). None of them complained when they couldn't save their command
history.
