Some users may provide custom download commands with spaces in their
arguments, like so:
BR2_HG="hg --config foo.bar='some space-separated value'"
However, the way we currently call those commands does not account
for the extra quotes, and each space-separated part of the command is
interpreted as separate arguments.
Fix that by calling 'eval' on the commands.
Because of the eval, we must further quote our own arguments, to avoid
the eval further splitting them in case there are spaces (even though
we do not support paths with spaces, better be clean from the onset to
avoid breakage in the future).
We change all the wrappers to use a wrapper-function, even those with
a single call, so they all look alike.
Note that we do not single-quote some of the variables, like ${verbose}
because it can be empty and we really do not want to generate an
empty-string argument. That's not a problem, as ${verbose} would not
normally contain space-separated values (it could get set to something
like '-q -v' but in that case we'd still want two arguments, so that's
fine).
