samples/bpf: Fix tracex5 to work with MIPS syscalls.
There are two problems:
1) In MIPS the __NR_* macros expand to an expression, this causes the
sections of the object file to be named like:
.
.
.
[ 5] kprobe/(5000 + 1) PROGBITS 0000000000000000 000160 ...
[ 6] kprobe/(5000 + 0) PROGBITS 0000000000000000 000258 ...
[ 7] kprobe/(5000 + 9) PROGBITS 0000000000000000 000348 ...
.
.
.
The fix here is to use the "asm_offsets" trick to evaluate the macros
in the C compiler and generate a header file with a usable form of the
macros.
2) MIPS syscall numbers start at 5000, so we need a bigger map to hold
the sub-programs.
