linux-perf: Exclude perf-read-vdso* from shared library dependency check

Fixes FTBFS on sparc64:

    dpkg-shlibdeps: error: no dependency information found for /usr/lib32/libc.so.6 (used by debian/linux-perf-4.9/usr/lib/perf_4.9-core/perf-read-vdso32)
    Hint: check if the library actually comes from a package.
