icu-native: do_install: Segmentation fault

There was a "Segmentation fault" error when build icu-native when the
TMPDIR is in a deep directory (for example, when len(readlink -f $TMPDIR
== 410)), use LARGE_BUFFER_MAX_SIZE for cmd rather than
SMALL_BUFFER_MAX_SIZE would fix the problem, this should be a misplay
because other cmd uses LARGE_BUFFER_MAX_SIZE.

+Use LARGE_BUFFER_MAX_SIZE for cmd rather than SMALL_BUFFER_MAX_SIZE,
+otherwise there was a Segmentation fault error when the command line is
+long, this should be a misplay since other cmd uses
