xlator: do not call dlclose() when debugging
Valgrind can not show the symbols if a .so after calling dlclose(). The
unhelpful ??? in the output gets resolved properly with this change:
==25170== 344 bytes in 1 blocks are definitely lost in loss record 233 of 324
==25170== at 0x4C29975: calloc (vg_replace_malloc.c:711)
==25170== by 0x52C7C0B: __gf_calloc (mem-pool.c:117)

==25170== by 0x52DA8D6: glusterfs_graph_init (graph.c:321)
==25170== by 0x52DB587: glusterfs_graph_activate (graph.c:695)
==25170== by 0x5046407: glfs_process_volfp (glfs-mgmt.c:79)
==25170== by 0x5043B9E: glfs_volumes_init (glfs.c:281)

==25170== by 0x50451A7: glfs_init@@GFAPI_3.4.0 (glfs.c:1031)
By not calling dlclose(), the dynamically loaded .so is still available
upon program exit, and Valgrind is able to resolve the symbols. This
will add an additional leak, so dlclose() is called for normal builds,
but skipped when configuring with "./configure --enable-valgrind" or
passing the "run-with-valgrind" xlator option.
