TestVectorUtilSupport increase delta for larger vector sizes

[tteofili]

Comparing results of vector functions with and without Panama support might lead to larger discrepancies as the vector dimensionality grows.
For example:

./gradlew test --tests TestVectorUtilSupport.testMinMaxScalarQuantize -Dtests.seed=A315683B50AE2A0 -Dtests.locale=bho -Dtests.timezone=GMT -Dtests.asserts=true -Dtests.file.encoding=UTF-8

fails with:

TestVectorUtilSupport > testMinMaxScalarQuantize {p0=4096} FAILED
    java.lang.AssertionError: expected:<1770.3743896484375> but was:<1770.3133544921875>

Thanks, makes sense
