Update `JarWriter` so that entry times are set with the default TimeZone
offset removed. The Javadoc for `ZipEntry.setTime` states:
The file entry is "encoded in standard `MS-DOS date and time format`.
The default TimeZone is used to convert the epoch time to the MS-DOS
data and time.
Removing the offset from our UTC time before calling `entry.setTime()`
ensures that we get consistent bytes in the zip file when the output
stream reapplies the offset during write.

Update the Maven and Gradle plugin to generate an `argfile` file
file under `META-INF/native-image` that contains `--exclude-config`
arguments that should be passed when generating a native image.
The contents of the file is generated for each nested jar that has a
`reachability-metadata.properties` file containing 'override=true'.
The `reachability-metadata.properties` file is expected to be generated
by the Graal native build tools plugin.
Closes gh-32738
Update `launch.script` so that the `run_user` variable is only set when
the user actually exists. Prior to this commit, if the jar file was
owned by a non-existing user the startup script could fail.
Fixes gh-29370
Previously, when writing a repackaged jar, an attempt to write all of
an entry's parent directories would always be made, irrespective of
whether or not the entry itself had already been written. This was
inefficient as, due to the way that the jar is written, once an entry
itself has been written, we know that all of its parent directories
will also have been written.
This commit updates the jar writer so that no attempt is made to
write parent directory entries if the entry itself has already been
written.
