nixos/systemd-boot-builder: Don't write .pyc files 
This has surfaced since d990aa7163.

The "simpleUefiGummiboot" installer test fails since this commit,
because that commit introduced a small check to verify whether the store
was altered.

While installing NixOS for the first time, the store is usually in
/mnt/nix/store and without the read-only bind mount that's preventing
programs from altering the store.

So after nixos-install is done creating the system closure and setting
it as the active system profile, the bootloader is written from the
closure inside the chroot. The systemd-boot-builder is invoked during
this step, which adds .pyc files for various Python modules of the
Python 3 store path, which in turn invalidates the hash of the Python 3
store path itself.

At the time the system is booted up again, the nix-store is verified and
fails with something like this:

path /nix/store/zvm545rqc4d97caqq9h7344bnd06jhzb-python3-3.5.3 was
modified! expected hash
b2c975f4b8d197443fbb09690fb3f6545e165dd44c9309d7d6df2fce0579ebeb, got
bccca19f39c9d26d857ccf1fb72818b2b817967e6d497a25a1283e36ed0acf01

Running the interpreter with the -B argument prevents Python from
writing those byte code files:
