Makefile: strip leading ./ in $(LIB_H)

Currently, $(LIB_H) is generated from two modes: if `git ls-files` is
present, it will use that to enumerate the files in the repository; else
it will use `$(FIND) .` to enumerate the files in the directory.

There is a subtle difference between these two methods, however. With
ls-files, filenames don't have a leading `./` while with $(FIND), they
do. This results in $(CHK_HDRS) having to substitute out the leading
`./` before it uses $(LIB_H).

Unify the two possible values in $(LIB_H) by using patsubst to remove the
`./` prefix at its definition.
