fix: add permission name when accessing a special file errors

fix #25055

Can you add a test to ensure it's actually fixed and doesn't regress in the future?

I found something weird with tests

import { assertThrows } from "jsr:@std/assert";
Deno.test({ permissions: { read: true } }, function execPathPerm() {
  console.log(Deno.permissions.querySync({ "name": "read" }));
  if (Deno.build.os === "linux") {
    assertThrows(
      () => {
        const a = Deno.readTextFileSync("/proc/net/dev");
        console.log(a);
      },
      Deno.errors.PermissionDenied,
      "Requires read access to <exec_path>, run again with the --allow-read flag",
    );
  }
});

if I run this on the main branch with deno test -A, it doesn't error as expected, seems somehow like even though I specified only read = true, the tests are passing allow-all permission in implicit way, so it doesn't throw

I tried it out and cargo test js_unit_tests::os_test runs fine with this, so I reverted to it.

Hmmm... it was passing locally and now it's failing. I probably wasn't running it correctly. I'm looking into this.

I'm going to revert my changes and follow up in a separate pr

LGTM. Thanks!
