build.jl is broken with mamba as conda provider

[axsk]

Just tried to build PyCall into a new environment, using the micromamba binary in ENV["CONDA_JL_CONDA_EXE"].

This gives the following error

ERROR: Error building `PyCall`:

and falls back to PyCall requiring the satisfied-skip-solve argument in build.jl:79 which is not supported by mamba.

Not sure whether this is an PyCall.jl or Conda.jl issue.
