delete allocated array properly (#2285)
delete allocated array properly (#2285)

In bcc_btf.cc, new_btf_sec is allocated with something like
   new_btf_sec = new uint8_t[tmp_sec_size]

Since the allocation is an array, the deletion should be
   delete[] new_btf_sec
instead of
   delete new_btf_sec

This patch fixed the problem.
