Tweak emcc CFLAGS

The build directory has a build dependency file (.o.d), SHA checksum
file of prebuilt artifact and else which are useless for WASM execution.
Additionally, these files increase the size of WASM, leading to longer
download time for WASM. Thus, only embed mandatory artifacts when build.

Enlarge the MEM_SIZE to make all ELF runnable.
