nearest probes: preserve user-entered lineno in chain

This patch adds an earlier well-formed probe point in the derivation
chain of .nearest probes so that the original lineno entered is
retained during stap -l.

Before:

$ stap -l 'kernel.statement("vfs_read@fs/read_write.c:396").nearest'
kernel.statement("vfs_read@fs/read_write.c:397").nearest

Now:

$ stap -l 'kernel.statement("vfs_read@fs/read_write.c:396").nearest'
kernel.statement("vfs_read@fs/read_write.c:396").nearest
