meta-renesas: weston: Fix gst-record uses MONOTONIC time for Cluster Demo

gst-record plugin uses gettimeofday to adapt gst buffer duration.
When WLAN network access internet, system timer is changed by NTP, then
the gst plugin system stopped.

This patch change to use MONOTONIC timer to detect buffer time frame.

v3:
 Need to use gst_clock_get_time function and GstClockTime.

+Subject: [PATCH] gst-record: switch to gettime function to CLOCK_MONOTONIC
+
+When system time is changed (e.g. from NTP) and buffer duration
+is bigger, the gst-record stops. It should use the CLOCK_MONOTONIC time.
+
+v2:
+ Need to use gst_clock_get_time function. Thus, GstClockTime is nsec
+timescale, it should be convert uint64_t by GST_TIME_AS_MSECONDS.
+
+v3:
+ Need to use gst_clock_get_time function and GstClockTime.
