LibELF: Ignore RISC-V attribute section program header

Browse source 
We have to skip our usual validations, as the checks might not hold for
this program header type (and the checks wouldn't really make sense for
PT_RISCV_ATTRIBUTES either).

PT_RISCV_ATTRIBUTES is defined here:
https://github.com/riscv-non-isa/riscv-elf-psabi-doc/blob/v1.0/riscv-elf.adoc#program-header-table
