Include cmMakefile.h before cm*Lexer.h to get stdint.h first

Some generated cm*Lexer.h headers define preprocessor macros normally
provided by <stdint.h>.  The latter is included indrectly by cmMakefile.h
since commit 2268c41a (Optimize custom command full-path dependency
lookup, 2013-08-06).  Adjust the order to avoid redefinition warnings.
