[libgpiod][PATCH] Make license type consistent between source files and COPYING file

[SZ Lin <sz.lin@xxxxxxxx>]

The license type of COPYING file is "LGPL-2.1+", but it declared
with "LGPL-2.1" in the beginning of source files

This patch fixes license type inconsistent issue in each source file

Signed-off-by: SZ Lin <sz.lin@xxxxxxxx>
