riscv: compat_vdso: install compat_vdso.so.dbg to /lib/modules/*/vdso/

'make vdso_install' installs debug vdso files to /lib/modules/*/vdso/.

Only for the compat vdso on riscv, the installation destination differs;
compat_vdso.so.dbg is installed to /lib/module/*/compat_vdso/.

To follow the standard install destination and simplify the vdso_install
logic, change the install destination to standard /lib/modules/*/vdso/.
