arm64: vdso32: rename 32-bit debug vdso to vdso32.so.dbg

Browse Source 
'make vdso_install' renames arch/arm64/kernel/vdso32/vdso.so.dbg to
vdso32.so during installation, which allows 64-bit and 32-bit vdso
files to be installed in the same directory.

However, arm64 is the only architecture that requires this renaming.

To simplify the vdso_install logic, rename the in-tree vdso file so
its base name matches the installed file name.
