When generating functions to print the arguments of system calls with
bitwise parameters (e.g. mmap), print the syscall parameter value first.
The resulting output looks like the %b specifier of printf(9).
Before:
mmap(0,0x8000,PROT_READ|PROT_WRITE,...
After:
mmap(0,0x8000,0x3<PROT_READ|PROT_WRITE>,...
