Description:
After compiling a program with golang, a masterdir/tmp/go directory is created with files in it that can only only be removed as root.

``./xpbs-src zap`` then complains about permissions like below

```
rm: cannot remove '/home/b/void-packages/masterdir/tmp/go/pkg/mod/golang.org/x/net@v0.0.0-20190328230028-74de082e2cca/dns/dnsmessage/example_test.go': Permission denied
