Subject: [PATCH RFC net-next v2 0/3] vsock/test: Improve transport_uaf test

Increase the coverage of a test implemented in commit 301a62dfb0d0
("vsock/test: Add test for UAF due to socket unbinding"). Take this
opportunity to factor out some utility code, drop a redundant sync between
client and server, and introduce a /proc/kallsyms harvesting logic.

Changes in v2:
- Speed up: don't bother checking EINTR or respecting timeout on connect()s
- Introduce get_transports(), warn on unsupported setup [Stefano]
- Comment the code, drop the sync, introduce vsock_bind_try() [Stefano]
- Link to v1: https://lore.kernel.org/r/20250523-vsock-test-inc-cov-v1-1-fa3507941bbd@rbox.co
