fix(linux-kernel): gate reads arch/$SRCARCH, and fails when it cannot read at all db48a78ffa

Caught by the first live BuildRun (linux-kernel-ci-h667z, 13s).

Two defects in the gate landed in d3aa310:

1. Wrong path. `make ARCH=x86_64` builds out of arch/x86, so the defconfig is
   arch/x86/configs/seanfarm_defconfig — not arch/x86_64/configs/. KARCH is the
   make ARCH, which is not the source-dir name on x86. Split out SRCARCH.

2. The gate was VACUOUS on that wrong path. Each check is
   `grep <sym> $SRC && ! grep <sym> .config`; when $SRC does not exist the
   first grep is non-zero, the && short-circuits, the if is false, and the loop
   reports "hard-gated symbols survived configure" having verified nothing.
   The build only failed later, incidentally, on the drift report's redirect.
   A gate that cannot read its input must fail, not pass — silently passing is
   worse than no gate because it reads as proof. Assert $SRC and .config are
   readable first.

pahole in kernel-builder:v9 is v1.31, comfortably over the 1.21 that
CONFIG_DEBUG_INFO_BTF needs for DWARF5, so BTF is genuinely supported.

Fixture-tested: green with BTF present; fails on a dropped BTF, on an
unreadable defconfig (regression test for defect 2), and on a missing pahole.
