compose: fix the description of modifiers in compose sequences
The Compose format has a feature which allows specifying certain modifiers must (or must not) be present with a given keysym in the sequence. The grammar in imLcPrs.c and the Compose man page both do not match what the code actually does (see the handling of the variables `modifier_mask` and `modifier` in parseline() in imLcPrs.c, which are eventually matched as `ev->state & modifier_mask == modifier`). Also explicitly list the accepted modifier names, since they are not standard (e.g. "Ctrl" instead of "Control").
