fusefrontend: sharedstorage: lock truncate agains concurrent accessLockSharedStorage_rebase1
Prevent reads and writes concurrent with the truncate operation. It's
racy on tmpfs and ext4 ( https://lore.kernel.org/all/18e9fa0f-ec31-9107-459c-ae1694503f87@gmail.com/t/ )
as evident by TestOpenTruncate test failures:
=== RUN TestOpenTruncate
cluster_test.go:209: POSIX compliance issue: non-exlusive create failed with err=file exists
doRead 16384215: corrupt block #0: cipher: message authentication failed
