sys-libs/libseccomp: revbump for loong patch 20220622

The previous revision of the loong patch still had fstat and newfstatat
declared as present on loong, while the upstreamed loong kernel ABI has
removed support for them. This caused build failures for sys-apps/file
and perhaps others, so bump to latest iteration of the upstream PR [1].
(As for quality of the patch, the PR is likely to be accepted as-is.)

The patch is again generated by diffing `make dist` output against the
official 2.5.4 tarball, due to the package being a base-system one.

This is ~loong-only, because the only thing that got bumped was the
loong patchset.
