libjxl easyconfig fails to install if asciidoc is installed in OS

[boegel]

libjxl added in #13453 fails for me with:

  File "/usr/bin/a2x", line 76
    print '%s: %s' % (PROG,msg)
                 ^
SyntaxError: invalid syntax

$ rpm -qf /usr/bin/a2x
asciidoc-8.6.8-5.el7.noarch

CMake option: JPEGXL_ENABLE_MANPAGES=OFF

[boegel]

@branfosj Hmm, no?

CMake Warning:

[branfosj]

Ah. They've added that option since 0.3.7. :(

It looks like it will need patching out: https://github.com/libjxl/libjxl/blob/9e9bce86164dc4d01c39eeeb3404d6aed85137b2/CMakeLists.txt#L287

Or adding asciidoc as a build dependency.

We could look to update libjxl as well (they released it just after i made the PR)

[boegel]

I looked into asciidoc once, it was... messy.

So bumping to libjxl 0.5 and using -DJPEGXL_ENABLE_MANPAGES=OFF then?

[branfosj]

Yes, bump libjxl to 0.5.
