python3: update target and native recipes to 3.5.4

Use the latest 3.5 version until the 3.6 migration is complete

Removed the following upstreamed patches:
  - python3/Fix-29519-weakref-spewing-exceptions-during-interp-f.patch
  - python3/upstream-random-fixes.patch

Rebased the following pathes:
  - python3/0001-cross-compile-support.patch

Regenerated the manifest based on the latest release version

Updated the license checksum for the latest version that updated the
copyright dates

-Subject: [PATCH] Issue #29157: Prefer getrandom() over getentropy()
-
-Copy and then adapt Python/random.c from default branch. Difference between 3.5
-and default branches:
-
-* Python 3.5 only uses getrandom() in non-blocking mode: flags=GRND_NONBLOCK
-* If getrandom() fails with EAGAIN: py_getrandom() immediately fails and
-  remembers that getrandom() doesn't work.
-* Python 3.5 has no _PyOS_URandomNonblock() function: _PyOS_URandom()
-  works in non-blocking mode on Python 3.5

-+
-+   Prefer getrandom() and getentropy() over reading directly /dev/urandom

-+

-+   and has access to hardware RNG, they are used as entropy sources.

-+   Note: the OpenSSL RAND_pseudo_bytes() function does not automatically reseed
