port: fix linux-build link error in optionsoverlay (_SHIFTL)

Browse Source 
gbi.h's gDP* DL macros use _SHIFTL/_SHIFTR without defining them; game TUs
pull them in via <ultra64.h>. This is the first port/src TU to build a
display list, and on GCC/ld the missing macro became an undefined symbol
(MinGW's include chain happens to provide it). Define the two pure macros
locally, verbatim from PR/mbi.h -- including mbi.h itself drags in N64 OS
headers that shadow libc.
