[PATCH GSoC v3 1/8] t5701: use test_file_size() to get the size of a file

[Pablo Sabater <pabloosabaterr@gmail.com>]

The 'basics of object-info' test runs 'wc -c | xargs' twice to get the
size of two.t. The pipe to xargs is only there to strip the blanks
that some platforms pad the output of wc with.

Use the test_file_size() helper, which outputs the size directly, and
store the result in a variable. Because 'git rev-parse two:two.t' is
also run twice, store its output in a variable as well.
