In AmigaDOS, read permission on a directory has the effect read and execute 

permission has in VFS; execute permission permission on a directory is ignored
by AmigaDOS:  when translating permissions from AmigaDOS to VFS, set up VFS
execute permission for AmigaDOS-readable directories.
Fixes PR kern/3787 from Michael van Elst <mlelstv@serpens.swb.de>.
