[Buildroot] [PATCH] core/pkg-meson: simplify sed-expression to add to [binaries]

[Yann E. MORIN]

There is no need to memorise the matched pattern; it's a left-over from
a previous attempt.

However, ensure the pattern is correctly anchored to the beginning and
end of the line, to avoid accidentally matching it anywhere else (e,g,
in a comment).
