[PATCH] arm64: clean up vdso and vdso32 files

[PATCH] arm64: clean up vdso and vdso32 files

[Magnus Damm]

From: Magnus Damm <damm+renesas@opensource.se>

Adjust the Makefile to remove vdso and vdso32 files during distclean.

The following vdso files get generated by the defconfig as of v5.13-rc5:
 arch/arm64/kernel/vdso/vdso.lds
 arch/arm64/kernel/vdso/vdso.so
 arch/arm64/kernel/vdso/vdso.so.dbg
