Alias 'make' to 'make vendor fmt lint' (#2152)

The current default of building a binary is not frequently used.

The new default is useful after switching branches, stashing/unstashing,
AI changes.

Note "fmt" and "lint" are separate steps because "fmt" can fix
formatting and imports in presence of compilation errors and "lint"
cannot. Without compilation errors, "lint" also does formatting.
