Introduce f_owner_ex.h

Browse Source 
Some headers define struct f_owner_ex, some struct __kernel_f_owner_ex,
we have to support both variants.

* configure.ac (AC_CHECK_TYPES): Check for "struct f_owner_ex"
and "struct __kernel_f_owner_ex" in <linux/fcntl.h>.
* f_owner_ex.h: New file.
* Makefile.am (strace_SOURCES): Add it.
