backupfile: fix bug when renaming not from wd
* lib/backupfile.c (backupfile_internal): Fix bug when DIR_FD
does not specify the working directory, and when RENAME.
Without the bug fix, FILE is treated as relative to the working
directory, not relative to DIR_FD, when renaming FILE.
This bug was introduced when DIR_FD and RENAME were introduced,
in 2018-10-24T02:10:21Z!eggert@cs.ucla.edu.
While we’re at it, when SDIR is nonnegative improve performance a
bit by passing an SDIR-relative old name to renameatu.

Move AM_V_GEN to recipe start
This is especially needed when building Emacs, as it uses
‘AM_V_GEN=@$(info GEN $@)', which means the GEN line is output by
GNU make just before the recipe runs, regardless of where AM_V_GEN
appears in the recipe. And it’s also good practice even if the
default Automake ‘AM_V_GEN=@echo GEN $@;’ is used, as it’s better
to output the GEN line consistently at the start of every recipe,
even if this precedes a preparatory command that almost always
works silently.
