Reduce the initial buffer size for open_memstream
Reduce the initial buffer size for open_memstream (used by vasprintf),
as most strings are usually smaller than that.
Realloc the buffer after finishing the string to further reduce size.
Problem appears in case of UCLIBC_HAS_GLIBC_CUSTOM_STREAMS=y,
see http://dev.openwrt.org/ticket/13024
