Nixpkgs: gobject-introspection has reference to /build

[doronbehar]

Describe the bug

Not sure if that's a big deal because it probably doesn't break anything but Today I discovered that gobject-introspection includes a shared object that references /build.

To Reproduce

$ ls -l $(nix-build -A gobject-introspection)/lib
total 276
dr-xr-xr-x 1 root root    648 Jan  1  1970 girepository-1.0
dr-xr-xr-x 1 root root     18 Jan  1  1970 gobject-introspection
lrwxrwxrwx 1 root root     24 Jan  1  1970 libgirepository-1.0.so -> libgirepository-1.0.so.1
lrwxrwxrwx 1 root root     28 Jan  1  1970 libgirepository-1.0.so.1 -> libgirepository-1.0.so.1.0.0
-r-xr-xr-x 1 root root 267968 Jan  1  1970 libgirepository-1.0.so.1.0.0
lrwxrwxrwx 1 root root     73 Jan  1  1970 libregress-1.0.so -> /build/gobject-introspection-1.64.0/build/tests/scanner/libregress-1.0.so

Expected behavior

Not sure what's up with that libregress-1.0.so so I don't know.
