python3-paramiko: update to version 2.10.3

2.10.2:

 - [Bug] Fix Python 2 compatibility breakage introduced in 2.10.1.
 Spotted by Christian Hammond.

2.10.3:

 - [Bug] Switch from module-global to thread-local storage when
 recording thread IDs for a logging helper; this should avoid one
 flavor of memory leak for long-running processes. Catch & patch via
 Richard Kojedzinszky.

 - [Bug] Certificate-based pubkey auth was inadvertently broken when
 adding SHA2 support; this has been fixed. Reported by Erik Forsberg
 and fixed by Jun Omae.
