bootimg: set default value for LABELS variable

With empty LABELS variable build_efi_cfg skips most of its
functionality producing warning message:
    'LABELS not defined, nothing to do'
This causes build failure for efi images.

Setting default value for LABELS to 'boot install' should fix
this issue.
