riscv: bug: Make RV32 use GENERIC_BUG_RELATIVE_POINTERS

Browse Source 
x86 did this in commit b0a848f4a4 ("x86/bugs: Make i386 use
GENERIC_BUG_RELATIVE_POINTERS")

powerpc did this in commit 1baa1f70ef ("powerpc: Allow relative
pointers in bug table entries")

Similar as x86 and powerpc does, make RV32 use
GENERIC_BUG_RELATIVE_POINTERS for "there is only one code path." and
"less #ifdef is more better".
