Subject: scripts/sorttable: riscv: fix undelcred identifier 'EM_RISCV' error

Fix the following build break 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.

build break log from [1]:
scripts/sorttable.c:352:7: error: use of undeclared identifier 'EM_RISCV'

[1] https://lore.kernel.org/lkml/e8965b25-f15b-c7b4-748c-d207dda9c8e8@i2se.com/

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