[committed] benchtests: make compare_strings.py accept string as attribute value

[Siddhesh Poyarekar]

From: Su Lifan <su-lifan@linux.alibaba.com>

Commit ac759b1fbf28a82d99afde9046f8b72c7cba5dae added attribute
"overlap" to bench-memmove-walk, whose value is a string. This change
makes compare_strings.py fail since benchout_strings.schema.json
requires the values of attributes to be number.

This patch relaxes such constraint.
