[PATCH v3 2/7] gdb/dwarf: move dwarf2_cu::section to cu.c

[Simon Marchi <simon.marchi@efficios.com>]

Following the previous patch that moves the dwo_unit structure from
dwarf2/read.c to dwarf2/dwo.h, dwarf2_cu::section has no reason to be
implemented in dwarf2/read.c anymore.  Move it to dwarf2/cu.c.
