[PATCH 26/26] cindex: use sysread for generating fingerprint

[Eric Wong <e@80x24.org>]

We use sysseek for this file handle elsewhere (since it's passed
to `git rev-list --stdin' multiple times), and sysread ensures
we can use a larger read buffer than the tiny 8K BUFSIZ Perl +
glibc is contrained to.

This also ensures we autodie on sysread failures, since the
autodie import for `read' was missing and we don't call `read'
anywhere else in this file.
