riscv: do not select MODULE_SECTIONS by default
Since commit aad15bc85c18 ("riscv: Change code model of module to
medany to improve data accessing"), kernel modules have not been built
with -fPIC, so they wouldn't have R_RISCV_GOT_HI20 or R_RISCV_CALL_PLT
relocations, and handling of those relocations is unnecessary.
If RELOCATABLE=y, kernel modules will be built with -fPIE, which would
reintroduce said relocations, so only select MODULE_SECTIONS when
RELOCATABLE.
