commit dda5faa65e872e115e4e830ce14fa11267c7efc3

    Include sys/rseq.h in tst-rseq-disable.c
    
    Starting with commit 2c6b4b272e6b4d07303af25709051c3e96288f2d
    "nptl: Unconditionally use a 32-byte rseq area", the testcase
    misc/tst-rseq-disable is UNSUPPORTED as RSEQ_SIG is not defined.
    
    The mentioned commit removes inclusion of sys/rseq.h in nptl/descr.h.
    Thus just include sys/rseq.h in the tst-rseq-disable.c as also done
    in tst-rseq.c and tst-rseq-nptl.c.

    (cherry picked from commit 637aac2ae3980de31a6baab236a9255fe853cc76)
