[Buildroot] [git commit branch/2022.05.x] package/zfs: fix pam support

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=1f92be091b27a56a08c500481db7617f0dc68ed9
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2022.05.x

The --enable option was added to CONF_ENV instead of CONF_OPTS. For this
defconfig

BR2_arm=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_LINUX_KERNEL=y
BR2_LINUX_KERNEL_USE_ARCH_DEFAULT_CONFIG=y
BR2_PACKAGE_ZFS=y
BR2_PACKAGE_LINUX_PAM=y

this yields

/bin/sh: line 1: --enable-pam=yes: command not found

While we're at it, also remove the =yes which we usually don't add.
