package/systemd: fix host build with 7.0+ kernel

Browse Source 
Linux v7.0 introduced a few more errno values that are aliases of other
errnos. This causes the following error:

In file included from ../src/basic/errno-list.c:13:
src/basic/errno-to-name.h:71:23: error: initialized field overwritten [-Werror=override-init]
   71 |         [EFSBADCRC] = "EFSBADCRC",
      |                       ^~~~~~~~~~~
src/basic/errno-to-name.h:71:23: note: (near initialization for ‘errno_names[74]’)
src/basic/errno-to-name.h:114:26: error: initialized field overwritten [-Werror=override-init]
  114 |         [EFSCORRUPTED] = "EFSCORRUPTED",
      |                          ^~~~~~~~~~~~~~
src/basic/errno-to-name.h:114:26: note: (near initialization for ‘errno_names[117]’)
cc1: some warnings being treated as errors

For target systemd this is not an issue as we don't support v7.0,
however it also occurs for host-systemd when building on a system with
kernel v7.0+.

Backport an upstream patch that excludes these two errnos from the
errno-to-name array. The upstream patch was applied to v261 and
backported to v258.5, but it was not backported to v256-stable (which is
EOL).
