Accepting request 1043748 from graphics

I tested this in a Leap 15.4 system with kimageformats 5.100.0
and gwenview5 and it could open/save jxl files correctly.
The test was built in 
home:alarrosa:branches:openSUSE:Backports:SLE-15-SP4:kimageformats

With this, we can submit jxl support to Backports for SLE15-SP5/
Leap 15.5

- Add patch (applied reversed) to revert the requirement for an
  updated liblcms2 library when we have an older one. This allows
  libjxl to build in SLE15 SP4/SP5 (and Leap 15.4/15.5):
  * 0001-Remove-LCMS-mutex.patch (forwarded request 1043745 from alarrosa)

Subject: [PATCH] Remove LCMS mutex (#112)
* Remove LCMS mutex
Requires mm2/Little-CMS@a35bacd, which is released in LCMS v2.11.
* Use a threadsafe alternative of gmtime in LCMS
Requires mm2/Little-CMS@68ee2ff, which is released in LCMS v2.13.
LCMS submodule was updated to version 2.13.1 instead.
