[PATCH] riscv: alternative: remove alternative boundary symbols in vdso

[Xiao Wang]

Instruction patching for vdso is based on elf header parsing to get the
beginning and ending of .alternative section, the __alt_start and __alt_end
symbols defined in vdso linker script are not used, so this patch removes
them.
