build/meson: cleanup "meson-post-install.sh"

- the variables in meson.build and in the meson-post-install.sh script
  should have the same names.

- the positional command line arguments should be assigned to variables,
  because the variable name acts like a documentation what the variable
  means (contrary to the argument number).

- the boolean flags should not map to other special values, like
  "enable_docs ? 'install_docs' : ''". The name "enable_docs" is
  good already, it shall be either passed as 1 or 0 and use the name
  consistently.
