  xkbcomp: Improve logging of virtual modifiers
  
  When logging about virtual modifier *explicit* mappings, we should
  always use only real modifiers or hexadecimal numbers to print the mask.
  
  Consider:
  
  ```
  virtual_modifiers M1, M2=0x200, M2=0x400;
  ```
  
  Before this commit we would get the following warning:
  
  ```
  WARNING: Virtual modifier M2 defined multiple times; Using M2, ignoring M1
  ```
  
  while we would prefer the less confusing:
  
  ```
  WARNING: Virtual modifier M2 defined multiple times; Using 0x400, ignoring 0x200
  ```
