test: add deterministic ioctl coverage and quotactl_fd in mountfs
ioctl (FamilyFS, KindFd@arg0) previously only fired implicitly via the Go
runtime/terminal. Add scenario_ioctl.go issuing a benign FIONREAD ioctl on
an opened temp file (registered as ioctl-basic) and ioctl_test.go asserting
enter_ioctl resolves to the temp file path, mirroring the fcntl suite.
quotactl_fd (FamilyFS, KindFd@arg0) had no coverage while its sibling
quotactl was tested in mountfs. Add a best-effort RawSyscall6 SYS_QUOTACTL_FD
call on an fd opened on the mount point in scenario_mountfs.go, extend
mountfsTraceArgs, and assert enter_quotactl_fd (MinCount>=1). The sys_enter
tracepoint fires on kernel entry regardless of privilege/quota support.
