tools: acrnctl fix cmd buffer is truncated when vmname too long

Browse Source 
'acrnctl start vmname' use a cmd buffer with a sizeof 128 bytes,
cmd[128] buffer will be truncated, when vmnane size is bigger than
29 bytes. In that situation, vmnane size still smaller than
MAX_VM_OS_NAME_LEN, so it should be fixed.
Macro PATH_LEN is useful to determine the cmd[] buffer length, so move
it from acrn_mngr.c into acrn_mngr.h
