fix print in case of python env isn't python2

[smCloudInTheSky]

Hello,

I tried to install bookworm on pop os 21.04. Had some errors on the post install script :

Paramétrage de bookworm (1.1.2+git20200823-1) ... File "/usr/share/com.github.babluboy.bookworm/scripts/mobi_lib/mobiml2xhtml.py", line 507 print 'Converting Mobi Markup Language to XHTML' ^ SyntaxError: Missing parentheses in call to 'print'. Did you mean print('Converting Mobi Markup Language to XHTML')?

this should do the work I did copy what you did on other print on this file

Sure but it is limited to debian Wouldn't it be better in 2024 to merge this within the project as python2 as been deprecated for a while ? If you want I can improve the PR.
