Currently the scripts in src/bin are installed by build/make/Makefile.

As part of #21507, for those scripts that should be considered part of sagelib, the installation should be done by src/setup.py instead, using the scripts and console-scripts features.

(Example, received from was: ​https://github.com/sagemathinc/smc/tree/master/src/smc_pyutil. See, in particular, the console_scripts section of setup.py: ​https://github.com/sagemathinc/smc/blob/master/src/smc_pyutil/setup.py#L58)

(Those scripts that don't belong into src/bin are moved to build/bin by #21559.
See also: #21570: Move non-scripts of src/bin/ elsewhere (and also move their install location; #21707: Split sage-env into sage-build-env and sage-env)
