Subject: [PATCH] build-sys: Detect whether struct statx is defined in

Starting with glibc 2.27.9000-36.fc29, include file sys/stat.h will have a
ff6046
definition for struct statx, in which case include file linux/stat.h should be
ff6046
avoided, in order to prevent a duplicate definition.

Extend our meson.build to look for struct statx when only sys/stat.h is
ff6046
included and, in that case, do not include linux/stat.h anymore.

Tested that systemd builds correctly when using a glibc version that includes a
ff6046
definition for struct statx.
