Subject: [PATCH] rust_binderfs: add transaction_report feature entry

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.

This might have been my fault because I added the Cc: stable tag.
However, no backport is needed. The patch is already applied to the 7.3
tree as commit 137d6ccf0ec8 ("rust_binderfs: add transaction_report
feature entry").
