sync:
As pointed out by Andrew Gregory there could be an error when adding
duplicates if they are two separate packages with the same name. Add a
check in alpm_add_pkg() to test whether the duplicate is actually the
same package, and if so, log a debug message and return success to skip
the package. If the duplicate is a different package return
ALPM_ERR_TRANS_DUP_TARGET and treat that error just like any other error
in pacman.
remove:
Change alpm_remove_pkg() to just log a debug message and return success
to skip duplicates. Remove the handling of ALPM_ERR_TRANS_DUP_TARGET in
pacman.
Also fixes FS#49377.
