Subject: qemu-iotests: drop unused _within_tolerance() filter

_within_tolerance() isn't used anymore and possibly creates temporary
files at predictable, world-writable locations. Get rid of it.

If it's needed again in the future it can be revived easily and fixed up
to use TEST_DIR and / or safely created temporary files.

-# Tolerance can be an absolute value or a percentage of the correct value
-# (see examples with tolerances below).
-# Outputs suitable message to stdout if it's not in range.

-# A verbose option, -v, may be used as the LAST argument

-# e.g.
-# foo: 0.0298 = 0.03 +/- 5%
