build: move syntax files to contrib/syntax/files

Having all of syntax files in the same directory makes it easier to
reference all of them at once on a makefile (such as with
`contrib/syntax/files/*.in`).

Also, this makes the path to the gtksourceview language-spec shorter.
Current path/new path:

* contrib/gtksourceview-5/language-specs/firejail-profile.lang
* contrib/syntax/files/firejail-profile.lang

Currently, adding a rule to the root Makefile to generate the
language-spec in the same directory as an input file would take at least
95 characters (with only a single dependency):

    contrib/gtksourceview-5/language-specs/%.lang: contrib/gtksourceview-5/language-specs/%.lang.in

With this commit, the above shortened to 59 characters:

    contrib/syntax/files/%.lang: contrib/syntax/files/%.lang.in

Which should make it more readable.

Relates to #2679 #5502.
