[Bug-xorriso] musl libc build fix

[Baruch Siach]

Hi xorriso mailing list,

xorriso build with a musl libc (http://www.musl-libc.org/) toolchain fails 
because of a missing header include as follows:

/home/buildroot/autobuild/run/instance-1/output/host/usr/bin/x86_64-linux-gcc 
-DHAVE_CONFIG_H -I.  -I./libburn -I./libisofs -I./libisoburn -I./xorriso 
-D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64  -DDEBUG -g 
-pedantic -Wall -Wextra -Wno-unused-parameter -Wno-char-subscripts 
-Wno-strict-aliasing -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE 
-D_FILE_OFFSET_BITS=64  -Os  -c -o libisofs/xorriso_xorriso-fs_local.o `test -f 
'libisofs/fs_local.c' || echo './'`libisofs/fs_local.c
In file included from libisofs/fs_local.c:21:0:
libisofs/aaip_0_2.h:36:1: error: unknown type name 'ssize_t'
 ssize_t aaip_encode(size_t num_attrs, char **names,
 ^

The patch below fixes this issue:
