nix: Add --print-build-logs flag
This causes 'nix' to print build log output to stderr rather than showing the last log line in the progress bar. Log lines are prefixed by the name of the derivation (minus the version string), e.g. binutils> make[1]: Leaving directory '/build/binutils-2.31.1' binutils-wrapper> unpacking sources binutils-wrapper> patching sources ... binutils-wrapper> Using dynamic linker: '/nix/store/kr51dlsj9v5cr4n8700jliyz8v5b2q7q-bootstrap-stage0-glibc/lib/ld-linux-x86-64.so.2' bootstrap-stage2-gcc-wrapper> unpacking sources ... linux-headers> unpacking sources linux-headers> unpacking source archive /nix/store/8javli69jhj3bkql2c35gsj5vl91p382-linux-4.19.16.tar.xz
