BUG/MEDIUM: hlua: Properly detect shudowns for TCP applets based on the new API

Browse Source 
The internal function responsible to receive data for TCP applets with
internal buffers is buggy. Indeed, for these applets, the buffer API is used
to get data. So there is no tests on the SE to properly detect connection
shutdowns. So, it must be performed by hand after the call to b_getblk_nc().

This patch must be backported as far as 3.0.
