builtin-upload-archive.c broken on openbsd

Looks like ctype again. Gotta be careful with that on BSD releases:

    $ gmake prefix=/opt/git all
    GIT_VERSION = 1.4.2.GIT
    gcc -o builtin-upload-archive.o -c -g -O2 -Wall -I/usr/local/include -DSHA1_HEADER='<openssl/sha.h>' -DNO_STRCASESTR builtin-upload-archive.c
    In file included from /usr/include/sys/poll.h:54,
                     from builtin-upload-archive.c:11:
    /usr/include/ctype.h:68: error: syntax error before ']' token
    /usr/include/ctype.h:69: error: syntax error before ']' token
    ...
    /usr/include/sys/poll.h:53:1: unterminated #ifndef
    /usr/include/sys/poll.h:28:1: unterminated #ifndef
    gmake: *** [builtin-upload-archive.o] Error 1

This fixes it.
