iproute2: upgrade 6.3.0 -> 6.4.0

Changelog: https://git.kernel.org/pub/scm/network/iproute2/iproute2.git/log/

Added a patch for including limits.h with musl builds, or else
we get failures such as:

| mdb.c: In function 'mdb_parse_vni':
| mdb.c:666:47: error: 'ULONG_MAX' undeclared (first use in this function)
|   666 |         if ((endptr && *endptr) || vni_num == ULONG_MAX)
|       |                                               ^~~~~~~~~
| mdb.c:666:47: note: 'ULONG_MAX' is defined in header '<limits.h>'; did you forget to '#include <limits.h>'?

+While building iproute2 6.4.0 with musl using Yocto Project, errors such
+as the following were encountered:
+
+| mdb.c: In function 'mdb_parse_vni':
+| mdb.c:666:47: error: 'ULONG_MAX' undeclared (first use in this function)
+|   666 |         if ((endptr && *endptr) || vni_num == ULONG_MAX)
+|       |                                               ^~~~~~~~~
+| mdb.c:666:47: note: 'ULONG_MAX' is defined in header '<limits.h>'; did you forget to '#include <limits.h>'?
+
+Include limits.h in bridge/mdb.c to fix this issue. This change is based
+on one in Alpine Linux, but the author there had no plans to submit:
