ANDROID: debug_kinfo: Replace strlcpy() with compatible and safer variant strscpy()

strlcpy() has now been formally removed from the kernel due to the risks it poses.

Fixes the following build error:

  drivers/android/debug_kinfo.c:161:2: error:
    call to undeclared library function 'strlcpy' with type 'unsigned long (char *, const char *, unsigned long)';
      ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
    161 |         strlcpy(info->last_uts_release, init_utsname()->release, sizeof(info->last_uts_release));
        |         ^

Fixes: d2627006 ("string: Remove strlcpy()")
