  dialog: Mitigate 'dlg_list' PKG fragmentation; Fix dlg_list_ctx memleak

By using pkg_str_extend() instead of pkg_realloc(), we avoid a constant
creation of PKG fragments (the buffer will eventually stop growing),
which seems to gradually fragment the private memory pool, as the MI
'dlg_list' is continuously polled by various monitoring software.

As a bonus, this patch also fixes a 'dlg_list_ctx' PKG memory leak
introduced in 543a40c8ff and only present on OpenSIPS 3.4+.
