[OE-core] [PATCH] scripts/pybootchart: Fix missing entries bug

[Richard Purdie]

If two entries have the same start time, the data store used will cause
all but one of the entries to be lost. This patch enhances the data
storage structure to avoid this problem and allow more than one
event to start at the same time.
