logs-show: do not use _SOURCE_MONOTONIC_TIMESTAMP field

The timestamp is not in CLOCK_MONOTONIC, but CLOCK_BOOTTIME,
while header monotonic timestamp is in CLOCK_MONOTONIC. Hence, we cannot
adjust timestamp by comparing with header monotonic timestamp and
_SOURCE_MONOTONIC_TIMESTAMP field.

Fixes a regression caused by affde1d7e79a634ee6053dbd4a57b3b51b74c170.
Fixes #33293.
