Convert context and buffy to use nanosecond timestamps.

The inotify interface has an unfortunate side effect of making Mutt
react too quickly to new mail.  Sometimes, the mail is only
half-delivered when the mailbox is checked.  Because Mutt is using the
stat mtime - seconds resolution - this means it won't realize there
are more messages delivered during the same second.

Nanosecond resolution fields were standardized in POSIX.1-2008, so
check for and use those if they are available.
