t/test-lib: fix TAP format for BASH_XTRACEFD warning

Browse Source 
When the Bash version is too old to support BASH_XTRACEFD we print a
warning to stderr. This warning is not prefixed with "#", which causes
TAP parsers to (wrongly) interpret the warning as part of the protocol.

Fix this issue by prefixing the warning with a "#" so that it is treated
as comment.
