Replace filepattern with pathspec for consistency

pathspec is the most widely used term, and is the one defined in
gitglossary.txt. <filepattern> was used only in the synopsys for git-add
and git-commit, and in git-add.txt. Get rid of it.

This patch is obtained with by running:

  perl -pi -e 's/filepattern/pathspec/' `git grep -l filepattern`
