Instead of adding SQLITE_API macros sqlite3.h while creating sqlite3.c, add them as part of generating the sqlite3.h target, while copying from sqlite.h.in to sqlite3.h. This fixes a build problem that was causing multiple SQLITE_API macros to be added to a single line of sqlite3.h, and the problem cited by #4016.

** The pager is used to access a database disk file.  It implements
** atomic commit and rollback through the use of a journal file that
** is separate from the database file.  The pager also implements file
** locking to prevent two processes from writing the same database
** file simultaneously, or one process from reading the database while
** another is writing.
