util: do not generate unrelated version information

The recent addition of the multicomponent version string for cr50,
requires further tweaking of the version generating script. In
particular, the CROS_EC_VERSION32 variable used by the "verson" cli
command is not supposed to include any information about subcomponents
of the image, it should reflect the EC version only.

Separating everything after the first space accomplishes that.

BRANCH=none
BUG=chrome-os-partner:55373
TEST=verified that RO_x and RW_x versions are printed properly:
  > vers
  Chip:    g cr50 B2
  Board:   0
  RO_A:    0.0.1/84e2dde7
  RO_B:  * 0.0.3/8fe06b9e
  RW_A:    cr50_v1.1.4992-7c9f891+ private
  RW_B:  * cr50_v1.1.4989-52b3cc6+
  ...
