t5526: use $TRASH_DIRECTORY to specify the path of GIT_TRACE log file

The test 'fetch --recurse-submodules -j2 has the same output behaviour' in 't5526-fetch-submodules.sh' fails when the test script is run with '-x' tracing (and using a shell other than a Bash version supporting BASH_XTRACEFD). The reason of that failure is the following command: GIT_TRACE=$(pwd)/../trace.out git fetch <...> 2>../actual.err because the trace of executing 'pwd' in the command substitution ends up in 'actual.err' as well, throwing off the subsequent 'test_i18ncmp'. Use $TRASH_DIRECTORY to specify the path of the GIT_TRACE log file instead of $(pwd), so the command's stderr remains free from tracing output. After this change t5526 passes with '-x', even when running with /bin/sh. Signed-off-by: SZEDER Gábor <szeder.dev@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
