mail/moztraybiff incorrectly works with WRKDIRPREFIX

[Andriy Gapon]

There is the following snippet in mail/moztraybiff/Makefile:

.if !exists(../thunderbird/Makefile)
BROKEN=         ${PORTNAME} needs the Thunderbird port in order to build
.else
TBVER!=         cd ../thunderbird && ${MAKE} -V PORTVERSION
.endif

When WRKDIRPREFIX is used TBVER gets set to an empty string.
It seems that this happens because current directory is somewhere under in
${WRKDIRPREFIX}, not in the ports tree.

The following patch worked for me, but I am not sure if everything is done
correctly.  Each time I work with ports I have to study Porter's Handbook like
I've never seen it before :-)
