exec: Explains non-hermeticity.

Explains that exec / exec_test / exec_rule, just like
genrule, does not guarantees hermeticity because PATH
is pass through.

For Kleaf projects, hermetic_exec / hermetic_exec_test
is recommended. There are no Roboleaf counterparts yet
at the moment of this writing.
