fix(tooling): run-atlas-naming.sh — use grep -a instead of strings (#833)

The gfx1201 preflight check piped `strings` into grep, which fails
silently on a Bazzite host where binutils is not installed and
`strings` is not on PATH. `grep -a` reads the binary directly as
text, works everywhere grep exists, and produces the same result.
