[PATCH] bin/estrip: avoid copying directories in FEATURES=installsources

Initially problem is noticed on gcc-11 as a full ${WORKDIR} syncing
into /usr/src/debug. It happens because `debug.sources` sometimes
contains directory. For example on bash-5 it has:

    $ grep -zv '/<[^/>]*>$' debug.sources | LANG=C sort -z -u  | sed -e 's/\x00/\n/g'
    bash-5.0/
    bash-5.0/alias.c
    ...

This causes syncing object files, config.log, final binaries
and other unexpected data. The change avoids syncking paths
that end with '/'.
