checkpatch: add a --strict test for structs with bool member definitions
A struct with a bool member can have different sizes on various architectures because neither bool size nor alignment is standardized. So emit a message on the use of bool in structs only in .h files and not .c files. There is the real possibility that this test could have a false positive when a bool is declared as an automatic, so limit the test to .h files where the only false positive is for declarations in static inline functions.
