refactor(GoMod): Use option -json with go list to get module names

The `-json` option allows specifying a comma separated list of
property names to include in the output. The `go list` command has a
mechanism for skipping certain processing steps which are not needed
for computing the values corresponding to those specified property
names, see [^1],[^2] and [^3]. Such a mechanism is not in place for the
`-f` option.

Migrate from `-f` to `-json` to benefit from above mechanism, removing
potential sources of issues. It could be that this allows to drop the
parameter `-buildvcs=false`, which is left for future investigation.

The primary reason for switching to `-json` is to extend the mentioned
mechanism [^4] in `go list` to conditionally skip computing embed
files in an analog way which would fix [^5].
