qapi: Move include/qapi/qmp/ to include/qobject/

The general expectation is that header files should follow the same
file/path naming scheme as the corresponding source file. There are
various historical exceptions to this practice in QEMU, with one of
the most notable being the include/qapi/qmp/ directory. Most of the
headers there correspond to source files in qobject/.

This patch corrects most of that inconsistency by creating
include/qobject/ and moving the headers for qobject/ there.

This also fixes MAINTAINERS for include/qapi/qmp/dispatch.h:
scripts/get_maintainer.pl now reports "QAPI" instead of "No
maintainers found".

Postcopy tests have been inadvertently disabled since commit
124a3c58b8 ("tests/qtest/migration: Move ufd_version_check to
utils"). That commit moved the ufd_version_check() function to another
file but failed to make sense of the ifdefs and includes:

The <sys/syscall> include was incorrectly dropped. It is needed to
pull in <asm/unistd.h> for __NR_userfaultfd.

The <sys/ioctl.h> was moved under the wrong ifdef.

doesn't reject the write. Still, write zeroes to the buffer to

Move the file to the qtest/migration/ directory along with the rest of
the migration files.
