[PATCH] libsemanage: fix src/genhomedircon.c build on `gcc-14` (`-Werror=alloc-size`)

[Sergei Trofimovich <slyich@xxxxxxxxx>]

`gcc-14` added a new `-Walloc-size` warning that makes sure that size of
an individual element matches size of a pointed type:

    https://gcc.gnu.org/PR71219

`libsemanage` triggers it on `calloc()` calls where member size is used
as `1` (instead of member count):

    genhomedircon.c: In function 'ignore_setup':
    genhomedircon.c:152:21:
      error: allocation of insufficient size '1' for type 'ignoredir_t'
        {aka 'struct IgnoreDir'} with size '16' [-Werror=alloc-size]
      152 |                 ptr = calloc(sizeof(ignoredir_t),1);
          |                     ^
