Fix regression from #8108 (Mar 2023). Since that change, gocross has
always been rebuilt on each run of ./tool/go (gocross-wrapper.sh),
adding ~100ms. (Well, not totally rebuilt; cmd/go's caching still
ends up working fine.)
The problem was $gocross_path was just "gocross", which isn't in my
path (and "." isn't in my $PATH, as it shouldn't be), so this line was
always evaluating to the empty string:
gotver="$($gocross_path gocross-version 2>/dev/null || echo '')"
The ./gocross is fine because of the earlier `cd "$repo_root"`

Also switch the wrapper script to use bash not posix shell. We now
depend on bash elsewhere for saner behavior in esoteric areas, so
might as well use it everywhere for consistency.

The subshell in which gocross gets built cd's to the corp checkout dir
near the top, so all future references to corp repository files should
be simple relative paths, and not reference $repo_root. When $repo_root
is an absolute path, it doesn't matter and everything works out, but on
some OSes and shells and invocations, $repo_root is a completely relative
path that is invalidated by the "cd".

Previously, the build ended up embedding an empty string, which made
the shell wrapper rebuild gocross on every invocation. This is still
reasonably fast, but fixing the bypass shaves 80% off gocross's overhead
when no rebuild is needed.

A bunch of us invoke tool/go from outside the repo that hosts gocross,
as a way of accessing our version-controlled toolchain. This removes
assumptions from gocross that it's being invoked within the repository
that contains its source code and toolchain configuration.

Sometimes, our cached toolchain ends up being an older version of
Go, older than our go.mod allows. In that scenario, gocross-wrapper.sh
would find a usable toolchain, but then fail to compile gocross.
This change makes the wrapper script check that the cached toolchain's
minor version is good enough to build tailscale.com, and re-bootstraps
in shell if not.

This makes gocross and its bootstrap script understand an absolute
path in go.toolchain.rev to mean "use the given toolchain directly".

This avoids accidentally overwriting variables from the input
environment, which might non-deterministically change the behavior
of gocross.
