[Buildroot] [PATCH] vim: be more careful when removing the documentation

[Thomas Petazzoni]

The current VIM_REMOVE_DOCS hook removes all .txt files from
/usr/share/vim. Unfortunately, this also removes the rgb.txt file,
which is needed at runtime for vim, as reported in bug #9466.

This commit changes VIM_REMOVE_DOCS to remove only
/usr/share/vim/vim80/doc/. Size-wise, it's equivalent because:

 - We are no longer removing a few README.txt in other directories,
   taking more space.

 - We are now removing the /usr/share/vim/vim80/doc/ folder entirely,
   which contained a few files not named *.txt

So overall, the size of /usr/share/vim/ before and after this patch is
still 11MB.

Fixes bug #9466.
