Fix zsh-related tests failure when TERM variable is set

When running zsh-related tests in the Ubuntu autopkgtest infrastructure, the
TERM environment variable is set to "linux". This causes the test-suite to
fail because zsh's output is impact by the TERM variable. We now override the
variable when running the zsh-related tests to make the test-suite pass.
