evmctl: use correct include for xattr.h

The xattr API/ABI is provided by both the c-library, as well as by the
libattr package. The c-library's header file is sys/xattr.h, whereas
libattr's header file can be found in attr/xattr.h.

Given none of the code here *links* against the libattr.so shared library, it
is wrong to *compile* against libattr's API (header file).

Doing so avoids confusion as to which xattr.h is used as the least problem,
and potential ABI differences as the worst problem due the mismatching header
file used.

So make sure we compile and link against the same thing, the c-library in
both cases.
