tree.sh: fix globbing in multi-tree command args

this solves a bug that does not yet manifest, because
this bug *can't* currently trigger any error due to
lbmk's design. this is therefore a preventative fix,
for reasons that will become clear.

we previously put arguments in a variable, in a way
that didn't handle globbing. now we avoid a variable
and use "$@" instead, which solves the problem.

this also means that the main logic in mk can be
cleaner, as trees-specific control logic is now
placed entirely in tree.sh's main.

this means that we can now also wrap x_ around trees()

this was never a problem in the past, because all of
the arguments for trees commands never have globbing;
config names are always e.g. foo_bar, not foo bar

in commands where globbing did need to be handled,
those commands were never trees commands. e.g.
you had ./mk inject filename

yes, this is a design improvement, or a preventative
bug fix. pick your poison.
