Hojun-Cho 3fe968c8a0 cmd+selfhost+test: gate alloc builtin behind same-module fn alloc ...

Mirrors the existing abort/assert gates in cstage check.c (strict
same-module lookup rather than scope_lookup_prefer, since lib/os.alloc
under a `use os;` import must not suppress the bare-alloc builtin in
client code). cgen.c shadows the resolution: only fire the rt_alloc
path when the typer left N_CALL.lhs->type == ty_err. wwstage gets a
new samemodfn helper for the matching gate.

Test fixtures: package-main repair for the 3 alloc rows in 700_e2e.c
that the parser was inheriting curmod="os" from the concat'd os.ww;
new shadow-test row asserts a same-module `fn alloc(n: i64) i64`
beats the builtin in cgen.
