[PATCH] libsolv: upgrade from 0.7.2 to 0.7.3

[Randy MacLeod <Randy.MacLeod@windriver.com>]

Also drop the musl specific fopencookie patches since musl
added support for fopencookie in:
   06184334 implement the fopencookie extension to stdio
in December 2017 so it has been in musl since v1.1.19.
There was no change in libsolv's configure log when building
with musl and these patches dropped.

libsolv NEWS
------------
Version 0.7.3
- selected bug fixes:
  * fixed a couple of null pointer derefs and potential memory
    leaks
  * made disfavoring recommended packages work if strong recommends
    is enabled
  * no longer disable infarch rules when they don't conflict with
    the job
- new features:
  * do favor evaluation before pruning allowing to (dis)favor
    specific package versions

-Subject: [PATCH 1/2] Add fallback fopencookie() implementation
-
-In environments where neither fopencookie() nor funopen()
-are implemented, we need to provide a suitable implementation
-of fopencookie() that we can use.
-
-Alex Kanavin: rebased CMakeLists.txt change to apply to latest upstream code.
