    tests/vpci: Use $(CC) instead of $(HOSTCC)
    
    Depending on the build environment, HOSTCC can be different than CC. With
    the recent `install` rule addition, this would put a binary of a wrong
    format in the destdir (e.g. building tests on x86 host for Arm target).
    
    Take the opportunity to adjust the `run` rule to only run the test if
    HOSTCC is CC, else print a warning message.
    
    Fixes: 96a587a05736 ("tools/tests: Add install target for vPCI")
