Fix "git help -a" terminal autosizing

When I split out the builtin commands into their own files, I left the include of <sys/ioctl.h> in git.c rather than moving it to the file that needed it (builtin-help.c).

Nobody seems to have noticed, because everything still worked, but because the TIOCGWINSZ macro was now no longer defined when compiling the "term_columns()" function, it would no longer automatically notice the terminal size unless your system used the ancient "COLUMNS" environment variable approach.

Trivially fixed by just moving the header include to the file that actually needs it.
