Subject: [PATCH] rtpjitterbuffer: Fix parsing of the mediaclk:direct= field

Due to an off-by-one when parsing the string, the most significant digit
or the clock offset was skipped when parsing the offset.

Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/-/merge_requests/910>

Upstream-Status: Backport [b5bb4ede3a42273fafc1054f9cf106ca527e3c26]
