Remove : from @param names in manually written headers

Makes style match the @param names in autogenerated headers and makes
clang -Wdocumentation stop complaining about all of them:

./xcb.h:523:11: warning: parameter 'display:' not found in the function
      declaration [-Wdocumentation]
 * @param display: A pointer to the display number.
          ^~~~~~~~
./xcb.h:523:11: note: did you mean 'display'?
 * @param display: A pointer to the display number.
          ^~~~~~~~
          display
