switch from typeof to the more portable __typeof__lede-17.01

Depending on the existance/lack of container_of define including libubox
or uci headers (e.g. #include <uci.h>) could result in compilation
errors like:
staging_dir/target-arm_cortex-a9_musl-1.1.16_eabi/usr/include/uci.h:643:10: error: expected declaration specifiers or '...' before '(' token
   return uci_to_package(e);
staging_dir/target-arm_cortex-a9_musl-1.1.16_eabi/usr/include/uci.h:643:10: error: '__mptr' undeclared (first use in this function)
   return uci_to_package(e);
