Alternative to cl/4661 discussed in #1044. It can be assumed that `$tmpdir/build-top` can be created safely without any risk, this way, we don't need to reuse the random directory creation primitive. Fixes #1044. Change-Id: Iec52477f3047fc40959b183c607312d5a40fc8c9 Signed-off-by: Raito Bezarius <raito@lix.systems>

| Nix shells' $NIX_BUILD_TOP are shorter |

Fixes |
|
Following the changes in 2.94.0 to shorten build directory paths, aimed at resolving UNIX domain socket length issues and improving nix-shell, we inadvertently introduced an excessively long path for the $NIX_BUILD_TOP environment variable used by Nix shells (their effective temporary /build directory).
To fix this, we replaced the build-top-$HASH directory name with simply build-top, reducing these paths by at least 30 characters.
We also added a test to ensure that Nix shells do not introduce more than 50 extra characters relative to their base directory (e.g., /tmp when $TMPDIR is not set).
