libsemanage: Fix snprintf warnings from gcc 7

Browse source 
Fixes the following warning from gcc7 by increasing the
buffer size to PATH_MAX.

semanage_store.c: In function ‘semanage_remove_directory’:
semanage_store.c:819:30: warning: ‘%s’ directive output may be truncated writing up to 255 bytes into a region of size 254 [-Wformat-truncation=]
   snprintf(s, sizeof(s), "%s/%s", path, namelist[i]->d_name);
                              ^~
semanage_store.c:819:3: note: ‘snprintf’ output 2 or more bytes (assuming 257) into a destination of size 255
   snprintf(s, sizeof(s), "%s/%s", path, namelist[i]->d_name);
   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
