[PATCH] rust_binderfs: add transaction_report feature entry

[Carlos Llamas <cmllamas@google.com>]

rust_binderfs is missing the equivalent of commit f37b55ded8ed ("binder:
add transaction_report feature entry"), which adds "transaction_report"
to the binderfs feature list. This helps userspace determine if the
BINDER_CMD_REPORT from the generic netlink API is supported.

Cc: stable@vger.kernel.org
Fixes: f14e0c8183bc ("rust_binder: report netlink transactions")
