Mint - Add environment variable RUN_ON_FAIL

[iternity-dotcom]

Refering to https://github.com/minio/minio/issues/11996:

Description

By setting the variable RUN_ON_FAIL all tests from minio-go are executed independent of failures.

Motivation and Context

A single failing test from the test package causes all the remaining tests to be skipped.

How to test this PR?

RUN_ON_FAIL=1
At least two tests must fail.

RUN_ON_FAIL=0
The behavior is not changed if the environment variable is not set or equals 0.
