RFR: 8286978: SIGBUS in libz during CDS initialization

[Calvin Cheung]

Please review this fix to ensure all requested bytes are transferred by calling `FileChannel.transferFrom` in a loop and checking its return value.

Tested by running the SharedArchiveConsistency.java test on linux-aarch64 30 times on each of the following tier3 options:

- `-XX:+CreateCoredumpOnCrash -XX:+UseSerialGC `
- `-XX:+CreateCoredumpOnCrash -XX:+UseParallelGC -XX:+UseNUMA`
