Subject: [PATCH] riscv: compat: vdso: Fix vdso_install target

When CONFIG_COMPAT=y the vdso_install target fails:

$ make ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu- vdso_install
  INSTALL vdso.so
make[1]: *** No rule to make target 'vdso_install'.  Stop.
make: *** [arch/riscv/Makefile:112: vdso_install] Error 2

The problem is that arch/riscv/kernel/compat_vdso/Makefile doesn't
have a vdso_install target, but instead calls it compat_vdso_install.
