scripts/sorttable: riscv: fix undeclared identifier 'EM_RISCV' error

Fix the following build failure reported in [1] by adding a conditional
definition of EM_RISCV in order to allow cross-compilation on machines
which do not have EM_RISCV definition in their host.

   scripts/sorttable.c:352:7: error: use of undeclared identifier 'EM_RISCV'

EM_RISCV was added to <elf.h> in glibc 2.24 so builds on systems with
glibc headers < 2.24 should show this error.
