Subject: [PATCH] diun: fix env.CGO_ENABLED set to "" instead of 0

env.CGO_ENABLED should be either 1 or 0, not a boolean.

If set to false, it is then rendered as an empty string,
which can be verified by running

$ nix derivation show nixpkgs#diun | jq '.derivations[].env | {CGO_ENABLED}'
{
  "CGO_ENABLED": ""
}

Also, the executable is, in fact, a dynamic one:
$ nix shell nixpkgs#diun
$ which diun
/nix/store/q8mc73sp6nz113m7ggb2m10r4brak82y-diun-4.33.0/bin/diun
$ ldd $(which diun)
	linux-vdso.so.1 (0x000076b5e6e4e000)
	libresolv.so.2 => /nix/store/8kvxvr3pmsypxiypq4g8zy13glnfr7nx-glibc-2.42-67/lib/libresolv.so.2 (0x000076b5e6e33000)
	libpthread.so.0 => /nix/store/8kvxvr3pmsypxiypq4g8zy13glnfr7nx-glibc-2.42-67/lib/libpthread.so.0 (0x000076b5e6e2e000)
	libc.so.6 => /nix/store/8kvxvr3pmsypxiypq4g8zy13glnfr7nx-glibc-2.42-67/lib/libc.so.6 (0x000076b5e6c00000)
	/nix/store/8kvxvr3pmsypxiypq4g8zy13glnfr7nx-glibc-2.42-67/lib/ld-linux-x86-64.so.2 => /nix/store/8kvxvr3pmsypxiypq4g8zy13glnfr7nx-glibc-2.42-67/lib64/ld-linux-x86-64.so.2 (0x000076b5e6e50000)

After setting it to 0,
$ nix derivation show .#diun | jq '.derivations[].env | {CGO_ENABLED}'
{
  "CGO_ENABLED": "0"
}

and the executable:
$ ldd $(which diun)
	not a dynamic executable

which is the intended effect.
