  $ make tools-all
  In file included from tools/env/env_flags.c:1:0:
  tools/env/../../common/env_flags.c: In function
    tools/env/../../common/env_flags.c:156:18: warning: implicit declaration
    of function ‘ARRAY_SIZE’ [-Wimplicit-function-declaration]
      for (i = 0; i < ARRAY_SIZE(env_flags_varaccess_mask); i++)
Seems like the other utilities just add a copy of ARRAY_SIZE since
there's nowhere to include it from (tools/imagetool.h,
tools/mxsimage.h). Let's do the same here.

Changes since v1:
  - Moved from tools/env/env_flags.c to common/env_flags.c
    as per suggestion from Tom Rini
