[LTP] kirk cannot handle env variable correctly

[Li Wang]

Hi Andrea, All,

We discovered that the LTP tests in the CI job all had a fixed timeout
value set,
regardless of LTP_TIMEOUT_MUL or LTP_RUNTIME_MUL . This only seemed
to happen when running Kirk, so to demonstrate the issue I manually ran the
following test:

=================
# ./kirk --framework ltp:root=/mnt/testarea/ltp --run-command mmap22 --env
LTP_TIMEOUT_MUL=1
