libtracefs utest: Fix min percent test
On PowerPC 64 which has 64K pages, it screws up the accounting of some
calculations used for tests. For instance, 1% of the ring buffer may not
be more than a page. So testing 1% and then subtracting the number of
events per page is going to lead to a negative number. This will obviously
fail.
Take into account that the subbuffer may be very large, and to make a
minimum percent to use in case a subbuffer size is greater than 1%.
