build: auto-generate syntax files

Changes:

* Generate firejail.vim from firejail.vim.in
* Generate firejail-profile.lang from firejail-profile.lang.in
* Update the manual syntax file steps on the new command checklist on
  CONTRIBUTING.md to use `make syntax` instead

Relates to #2679 #5502 #5577 #5612.
