Contrail-vrouter can't handle core ID which is bigger than 63

[Yi-y-yang]

In skylake platform, we have two sockets, each socket has 28 cores, if we enable hyperthread, it totals 112 logical cores, current contrail-vrouter can't handle core id bigger than 63, but for AT&T use case, we should be able to assign logical core 111 to contrail-vrouter, but it is impossible now.

Fix maximum core id limitation

Currently vrouter used uint64_t to save core mask, so it only
can support maximum core id 63, it can support 128 or more if we
use cpu_set_t to save core mask, this patch fixes this limitation
by using cpu_set_t instead of uint64_t.

Closes-bug: #1748068
