[PATCH v6 6/9] eal/arm: fix C++ build for 32-bit memcpy

[David Marchand]

This was caught while checking ARM arch headers.

In file included from buildtools/chkincs/chkincs-cpp.p/rte_memcpy_32.cpp:1:
/home/runner/work/dpdk/dpdk/lib/eal/arm/include/rte_memcpy_32.h:302:1:
	error: expected declaration before ‘}’ token
  302 | }
      | ^

Fixes: 719834a6849e ("use C linkage where appropriate in headers")
