Unable to locate the libc in android

[catlowlevel]

Environment:

• Frida-Gum: 17.1.3
• Target Platform: Android 15
• Architecture: arm64-v8a

Issue:
The following function doesn't seem to find libc when used as a Zygisk module with statically linked Frida-Gum:
https://github.com/frida/frida-gum/blob/d83ae3ea30f7de5dad23d763a0724b5e9d451e47/gum/backend-linux/gumprocess-linux.c#L1188

This might be related to how ZygiskNext works, but I'm not completely sure.

I worked around it by calling dladdr() on the exit function instead, like this:

@@ -1185,7 +1185,7 @@ gum_try_init_libc_info (void)
   if (!gum_try_resolve_dynamic_symbol ("__libc_start_main", &gum_libc_info))
 #endif
   {
-    if (!gum_try_resolve_dynamic_symbol ("exit", &gum_libc_info))
+    if (dladdr (&exit, &gum_libc_info) == 0)
       return NULL;
   }

That seems to fill gum_libc_info correctly.
Not sure if this is the best or cleanest way to handle it, though.
