Prometheus uses an older version of fsnotify, which uses a system call
(unix.InotifyInit) that is not implemented for mips64/mips64el.

This patches Prometheus to use a newer version of fsnotify that uses a
different system call (unix.InotifyInit1) that should be available on
all Linux systems.

Fixes #9494.
