cutils: fix memory leak in get_relocated_path()
get_relocated_path() allocates a GString object and returns the
character data (C string) to the caller without freeing the memory
allocated for that object as reported by valgrind:
24 bytes in 1 blocks are definitely lost in loss record 2,805 of 6,532
at 0x4839809: malloc (vg_replace_malloc.c:307)
by 0x55AABB8: g_malloc (in /usr/lib64/libglib-2.0.so.0.6600.8)

Let's use g_string_free(gstring, false) to free only the GString object
and transfer the ownership of the character data to the caller.
