daemon: Build in /tmp/guix-build-*.

You can influence the directory where the daemon stores build trees
@i{via} the @code{TMPDIR} environment variable. However, the build tree
within the chroot is always @file{/tmp/nix-build-@var{name}.drv-0},
within the chroot is always @file{/tmp/guix-build-@var{name}.drv-0},
where @var{name} is the derivation name---e.g., @code{coreutils-8.24}.
This way, the value of @code{TMPDIR} does not leak inside build
environments, which avoids discrepancies in cases where build processes
