While trying the coredump test on qemu-system-riscv64, I observed test
failures for various reasons.

This series makes the test works on qemu-system-riscv64.

  selftests: coredump: Raise timeout to 2 minutes
  selftests: coredump: Fix test failure for slow machines
  selftests: coredump: Properly initialize pointer
