superherointj 2ea8b001f6 beam/fetch-mix-deps: replace mixEnv with MIX_ENV
Currently, when fetchMixDeps is executed without mixEnv argument.
"mixEnv" envvar is empty at installPhase, instead of having value "prod".
This happens because optional attrs values are not included in @attrs variable.
Thrus being necessary to replace mixEnv for MIX_ENV, which holds value "prod".
