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

Extend our meson.build to look for struct statx when only sys/stat.h is
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
definition for struct statx.
