build-sys: meson: use target_machine.cpu_family() for CANONICAL_HOST

target_machine provides information about the machine on which the compiled
binary's output will run.

cpu_family() returns CPU family name (such as x86_64, not more specific amd64)

database: use existing database matching same architecture prefix

State database binary file format may depend on system architecture,
for instance gdbm binary format depends on architecture word size,
making x86 and x64 gdbm files incompatible.

If this is the case, it is handled by adding system architecture name to
database file name using automatically configured CANONICAL_HOST string.
Meson build define CANONICAL_HOST to be system architecture name, while
autotools build extends this with vendor and and operating system components.

Switch autotools build to use host_cpu for CANONICAL_HOST to match Meson
configuration. For backwards compatibility always use existing database file
matching CANONICAL_HOST prefix if it exists.
