+strace: fix system call matching code in get_scno for be8 arm
+
+on ARM V7 operating in big endian mode strace does not work:
+
+root@genericarmv7ab:~# strace ls
+pid 1356 unknown syscall trap 0x000000ef
+
+it happens because ARM V7 when runs as big endian operates in be8 mode,
+where instruction are still in little endian form. Strace get_scno reads
+instructions and matches it to certain pattern, but in armeb case it needs
+to byteswap it before that.
