alloc/test: Add test for interleaved TBF chains

MS iniated TCP connections generally result in a sequence
of short time UL and longer lasting DL TBFs, being interleaved
between several MS. This scenario is not covered by the existing
tests.

This commit adds a test, that allocates as man as possible TBFs
several times with different test modes without clearing the BTS (and
thus the TBF list) in between. The number of allocated DL TBFs in
each round is expected to be constant.
