util: Split out exec_dir from os_find_datadir
With this change, main() calls qemu_init_exec_dir and uses argv[0] to init exec_dir. The saved value can be retrieved with qemu_get_exec_dir later. It will be reused by module loading. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
