commonlib/lz4: Avoid unaligned memory access on RISC-V

From the User-Level ISA Specification v2.0:

"We do not mandate atomicity for misaligned accesses so simple
        implementations can just use a machine trap and software handler to
        handle misaligned accesses." (— http://riscv.org/specifications/)

Spike traps on unaligned accesses.
