binfmt_elf: cleanups
This cleans up a few bits in binfmt_elf.c and binfmts.h: - the hasvdso field in struct linux_binfmt is unused, so remove it and the only initialization of it - the elf_map CPP symbol is not defined anywhere in the kernel, so remove an unnecessary #ifndef elf_map - reduce excessive indentation in elf_format's initializer - add missing spaces, remove extraneous spaces No functional changes, but tested on x86 (32 and 64 bit), powerpc (32 and 64 bit), sparc64, arm, and alpha.
