Improve josm launchers (patch by sebastic)

Patch notes from sebastic, modified. See #22193.

  • Use /bin/bash instead of /usr/bin/env bash usrmerge systems have both /bin/bash and /usr/bin/bash, non-usrmerge systems only have /bin/bash. Distributions that have differing behaviors between /bin/bash and /usr/bin/bash should update/fix their version of bash.
  • Set ALTERNATIVE_JDK only if /etc/alternatives/java exists. While not only Debian based distributions use the alternatives system, not all distributions do.
  • Use 4 spaces for indentation consistently. Some indentation used tabs, others 2 spaces.
  • Simplify java_version function.
  • Don't use command -v to test whether dpkg is available. The command may be an alias which results in output like:

dpkg is aliased to 'd*-p*-k*-g*'

  • Fix issues reported by shellcheck. SC2086 is disabled for $JAVA_OPTS because that only works unquoted.
