[collectd] [PATCH 1/2] Fix buffer length in parse_identifier_vl function.

[Andres J. Diaz]

In parse_identifier_vl function (common.c), the value passed to
sstrncpy as buffer length is the sizeof a char pointer, which
is 4bytes for 32bit arch and 8bytes for 64 bit ones.

This patch fix the length and truncate the buffer to the same size as
destination buffer.
