Andreas Fenkart c5c41c45b1 tools/env: reuse fw_getenv in fw_printenv function ...

Try to avoid adhoc iteration of the environment. Reuse fw_getenv
to find the variables that should be printed. Only use open-coded
iteration when printing all variables.
For backwards compatibility, keep emitting a newline when
printing with value_only.
