Makefile.mk: address minor issues
- Fix `NROFF` auto-detection with certain shell/make-build combinations:

  When a non-MSYS2 GNU Make runs inside an MSYS2 shell, Make executes
  the detection command as-is via `CreateProcess()`. It fails because
  `command` is an `sh` built-in. Ensure to explicitly invoke the shell.

- Initialize user-customizable variables:

  Silences a list of warnings when running GNU Make with the option
  `--warn-undefined-variables`. Another benefit is that it's now easy
  to look up all user-customizable `Makefile.mk` variables by grepping
  for ` ?=` in the curl source tree.

  Suggested-by: Gisle Vanem
  Ref: https://github.com/curl/curl/pull/9764#issuecomment-1330674433

- Fix `MKDIR` invocation:

  Avoid a warning and potential issue in envs without forward-slash
  support.
