Sakib Sajal b44849c32c oeqa/core/target/qemu.py: display contents of dumped files
During do_testimage, if the target is not started within a certain
timeout, TEST_QEMUBOOT_TIMEOUT, host data is dumped to files for
each command in
${TMPDIR}/log/runtime-hostdump/<datetime>_qemu/host_<seq>_<command>.

Display the first 20 lines of top output and the last 20 lines of
bootlog to standard output for more context for the target not being
started up.

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
