nfscl: Fix IO_APPEND writes from kernel space

Commit 867c27c23a5c modified the NFS client so that
it did IO_APPEND writes directly to the NFS server
bypassing the buffer cache, via a call to
nfs_directio_write().  Unfortunately, this (very old)
function assumed that the uio iov was for user space
addresses.  As such, a IO_APPEND VOP_WRITE() that
was for system space, such as ktrace(1) does, would
write bogus data.

This patch fixes nfs_directio_write() so that it
handles kernel space uio iovs.

zfs-dkms rpm: simplify scriptlets, fix uninstall

Two problems led to unexpected behaviour of the scriptlets:

1) Newer DKMS versions change the formatting of "dkms status":

   (old) zfs, 2.1.2, 5.14.10-300.fc35.x86_64, x86_64: installed
   (new) zfs/2.1.2, 5.14.10-300.fc35.x86_64, x86_64: installed

   Which broke a conditional determining whether to uninstall.

2) zfs_config.h not packaged properly, but was attempted to be read
   in the %preun scriptlet:

   CONFIG_H="/var/lib/dkms/zfs/2.1.2/*/*/zfs_config.h"

   Which broke the uninstallation of the module, which left behind a
   dangling symlink, which broke DKMS entirely with this error:

     Error! Could not locate dkms.conf file.
     File: /var/lib/dkms/zfs/2.1.1/source/dkms.conf does not exist.

This change attempts to simplify life by:

*  Avoiding parsing anything (less prone to future breakage)
*  Uses %posttrans instead of %post for module installation, because
   %post happens before %preun, while %posttrans happens afterwards
*  Unconditionally reinstall module on upgrade, which is less
   efficient but the trade-off is that it's more reliable

Alternative approaches could involve fixing the existing parsing bugs
or improving the logic, but this comes at the cost of complexity and
possible future bugs.

pf: include anchor path when hashing a rule

Otherwise all anchors hash to the same value.

Note this can result in checksum mismatches between pfsynced hosts,
but it has to be sorted out as the previously computed checksum
would fail to indicate changed anchors.
