Explicitly allow maintainers to add a trailing comma for VC-friendly
multiline values:
XS-Go-Import-Path:
example.com/foo,
example.com/bar,
Currently all code that consumes the map returned from
`getGolangBinaries` ignores the empty string entry, so this commit
should not change behavior at all. However, this commit improves
readability by making it easy to see what happens in this corner case;
developers don't need to look at every caller of `getGolangBinaries`
to see how the empty string entry is handled. It is also defensive;
it avoids surprises for any future consumers of `getGolangBinaries`.
For example:
XS-Go-Import-Path:
example.com/foo
example.com/bar
This avoids forcing package maintainers to look up whether a trailing
comma after the final item is allowed or not. (Separating by
whitespace or permitting a trailing comma makes it easier to construct
a readable and VC-friendly multiline list of values.) Spaces cannot
exist in a module path, so there is no risk of parsing ambiguity.
The make subcommand doesn't produce space-separated lists, and
dh-golang doesn't yet support it, so this is just a step towards
generally allowing it everywhere.

This PR relaxes how
XS-Go-Import-Pathvalues are parsed to improve maintainer friendliness:XS-Go-Import-Path(in particular, ignore a trailing comma).
