vdso: remove per-arch declaration for vdso_redirect_calls

Browse Source 
It's the same on all archs (as it's called from generic code),
no need to redeclare it. <parasite-vdso.h> is included in all
per-arch headers. Drop vdso_symtable forward declaration as
<parasite-vdso.h> includes <util-vdso.h> header which defines
the structure.
