net/rsync: Update to 3.2.6

Major changes:

• fix file-list validator in --files-from for files that ends without a line-terminating character
• safety check when using --remove-source-files in a local copy that prevents removing file shared between src and dest
• fix internal MD4 checksum code who causes sporadic invalid sums
• rrsync: added "copy-devices" to the list of known args, but left it disabled by default
• rename --protect-args to --secluded-args, environment-variable override did not change its name
• configure option --with-protected-args was renamed to --with-secluded-args This option makes --secluded-args the default rsync behavior
