iproute2: fix build on GCC 14
Upstream patches:
401-bridge-vlan.c-bridge-vlan.c-fix-build-with-gcc-14-on.patch
402-bpf-fix-warning-from-basename.patch
403-bpf-include-libgen.h-for-basename.patch
The patch (400-rdma-include-libgen.h-for-basename.patch) was not
submitted upstream but just adds a missing include for basename.

+Subject: [PATCH] bridge/vlan.c: bridge/vlan.c: fix build with gcc 14 on musl
+ systems
+
+On glibc based systems the definition of 'struct timeval' is pulled in
+with inclusion of <stdlib.h> header, but on musl based systems it
+doesn't work this way. Missing definition triggers an
+incompatible-pointer-types error with gcc 14 (warning on previous
+versions of gcc):
+
+../include/json_print.h:80:30: warning: 'struct timeval' declared inside parameter list will not be visible outside of this definition or declaration
+ 80 | _PRINT_FUNC(tv, const struct timeval *)
+ | ^~~~~~~
+../include/json_print.h:50:37: note: in definition of macro '_PRINT_FUNC'
+ 50 | type value); \
+ | ^~~~

+Subject: [PATCH] bpf: fix warning from basename()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The function basename() expects a mutable character string,
+which now causes a warning:
+
+bpf_legacy.c: In function ‘bpf_load_common’:
+bpf_legacy.c:975:38: warning: passing argument 1 of ‘__xpg_basename’ discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
+ 975 | basename(cfg->object), cfg->mode == EBPF_PINNED ?
+ | ~~~^~~~~~~~
+In file included from bpf_legacy.c:21:
+/usr/include/libgen.h:34:36: note: expected ‘char *’ but argument is of type ‘const char *’
+ 34 | extern char *__xpg_basename (char *__path) __THROW;
+
+Fixes: f20ff2f19552 ("bpf: keep parsed program mode in struct bpf_cfg_in")
