Improve the start script to accept Java 11

[egli]

With this change all versions above Java 1.5 (including Java 11) should be valid run times.

@egli Have you also checked that it actually works with Java 11?

Hi @bertfrees I tested via shell, i.e. bash:

$ java -version
openjdk version "1.8.0_342"
OpenJDK Runtime Environment (build 1.8.0_342-8u342-b07-0ubuntu1~22.04-b07)
OpenJDK 64-Bit Server VM (build 25.342-b07, mixed mode)
$ java -version 2>&1 | head -1 | cut -d'"' -f2 | sed '/^1\./s///' | cut -d'.' -f1
8
$ java -version
openjdk version "11.0.16" 2022-07-19
OpenJDK Runtime Environment (build 11.0.16+8-post-Ubuntu-0ubuntu122.04)
OpenJDK 64-Bit Server VM (build 11.0.16+8-post-Ubuntu-0ubuntu122.04, mixed mode, sharing)
$ java -version 2>&1 | head -1 | cut -d'"' -f2 | sed '/^1\./s///' | cut -d'.' -f1
11

And yes, I also built a version of the pipeline1 (using Java8) and ran it under Java11 (with the patched launcher script). I then tested the ConfigurableValidator script with daisy202 and with DTBook and also the DTBAudioEncoder. They both worked.

Ok, so I guess some things will work, but other things will not. It would be nice to have a warning.

@NPavie Is your patch that updates Pipeline 1 to Java 8 in a state in which a PR can be made from it? Do you think that after applying it a warning is still required?

[NPavie]

@bertfrees i'll have to check again, i have not touch the pipeline 1 build in a while.
I'll see if i can validate the code for a PR today, so that we should be able to merge both.
