x11-wm/blackbox: Fix build with Clang 6, Fix TOOLS_ONLY option

Clang 6 (on 12-CURRENT) reports the following error during build:

EWMH.cc:250:7: error: non-constant-expression cannot be narrowed from type
'long' to 'unsigned long' in initializer list [-Wc++11-narrowing]
    { static_cast<long>(x), static_cast<long>(y) };
      ^~~~~~~~~~~~~~~~~~~~

There was also a bug introduced 4 years ago which removed the MAN1 variable a
later INSTALL_MAN macro relied on [1]. This caused a build/install failure
when the TOOLS_ONLY option was enabled.

This change fixes those two issues.

While I'm here level up port compliance:

  - Add LICENSE_FILE
  - Convert to OPTIONS helpers
  - Regenerate patches
