3rdparty.lua: Fix compilation of Lzma for arm64 architecture

[FlykeSpice]

The builder was failing in compiling the Lzma source code due to the global compiler flag -Werror -Wstrict-prototype triggering errors when compiling code specific to arm64 architecture.

This PR sets the -Wno-error=strict-prototypes flag when building the Lzma library

[FlykeSpice]

It was causing the following build error:
