[PATCH xserver] test: Fix stray Makefile reference to removed os test

[Rhys Kidd]

Fixes the following warning:

test/Makefile.am:69: warning: variable 'os_LDADD' is defined but no program or
test/Makefile.am:69: library has 'os' as canonical name (possible typo)

Introduced upon the removal of test/os in:

commit 6a5a4e60373c1386b311b2a8bb666c32d68a9d99

    Remove SIGIO support for input [v5]

    This removes all of the SIGIO handling support used for input
    throughout the X server, preparing the way for using threads for input
    handling instead.

    Places calling OsBlockSIGIO and OsReleaseSIGIO are marked with calls
    to stub functions input_lock/input_unlock so that we don't lose this
    information.

    xfree86 SIGIO support is reworked to use internal versions of
    OsBlockSIGIO and OsReleaseSIGIO.

    v2: Don't change locking order (Peter Hutterer)
    v3: Comment weird && FALSE in xf86Helper.c
        Leave errno save/restore in xf86ReadInput
        Squash with stub adding patch (Peter Hutterer)
    v4: Leave UseSIGIO config parameter so that
        existing config files don't break (Peter Hutterer)
    v5: Split a couple of independent patch bits out
        of kinput.c (Peter Hutterer)
