Add the definition for BUILD and initialize it to zero. This avoids
'bash -u vmtest.sh` from throwing 'unbound variable' when BUILD is not
set to 1 and is later checked for its value.

Changes in v2:
- remove fixes tag because it doesn't fix breakage of kselftest, and
  just supports otherwise invoking with bash -u
