[PATCH 19.11] config: add arch define for Arm

[Ruifeng Wang]

[ upstream commit 9cc217a28310d21fba56e5eceb740b4feb7e0949 ]

As per design document, RTE_ARCH is the name of the architecture.
However, the definition was missing on Arm with meson build.
It impacts applications that refers to this string.

Added for Arm builds.

Fixes: b1d48c41189a ("build: support ARM with meson")
