Make dl-fxstatat64.c include of fxstatat64.c use <> not ""

[Roland McGrath]

I think this is in the "obvious" category.  Nearly all #include's in
libc source should use <> syntax rather than "" syntax.  The only
exceptions are "../foo" cases (e.g. "../test-skeleton.c" and
"../libio/libioP.h").  In many places, especially in test cases, it
really doesn't matter either way and there's no particular reason to go
and change them all.  But in actual library code, anything that's not
"../foo" should use <> instead, and any "../foo" cases should have some
particular legitimate reason.  For the most part, we prefer explicit
things like #include <sysdeps/foo/bar/baz.c>.  There are some cases
where the naive conversion breaks, such as:

nptl/sysdeps/unix/sysv/linux/sigtimedwait.c:2:#include "../../../../../sysdeps/unix/sysv/linux/sigtimedwait.c"

Here the obvious:

#include <sysdeps/unix/sysv/linux/sigtimedwait.c>

would actually make the file include itself.  But probably it should
change to:

#include <nptl/../sysdeps/unix/sysv/linux/sigtimedwait.c>

so it's not dependent on the location of the including file.
