glob: fix includes

[Bruno Haible]

glob.c uses 'true' and 'false' without including <stdbool.h>. This breaks the
compilation on IRIX:

"glob.c", line 1391: error(1020): identifier "true" is undefined
              if ((flags & GLOB_ONLYDIR) && !DIRENT_MIGHT_BE_DIR (d))
                                             ^
I'm fixing it like this:


2008-04-11  Bruno Haible  <address@hidden>

        * lib/glob.c: Include <stdbool.h>. Needed at least with IRIX cc.
        * modules/glob (Depends-on): Add stdbool.
