Support installing modules.options file

Usage:
```
BOARD_(VENDOR|VENDOR_RAMDISK)_KERNEL_MODULES_OPTIONS_FILE(_ver) := \
  $(wildcard <path of modules.options in source tree>)
```

Then the modules.options would be installed as
(vendor_dlkm|vendor_ramdisk)/lib/modules/(ver/)modules.options.

Also fix bug where the kernel version subdir is missing when generating
modules.blocklists file.
