Revert "package/libopenssl: fix build on riscv32"

This reverts commit 2bb26c1a1d24cdbb946bc2a77680dbc8f9c0d537.

There was some negative feedback from Arnd Bergmann on that patch:
    https://github.com/openssl/openssl/commit/5b5e2985f355c8e99c196d9ce5d02c15bebadfbc#commitcomment-44782859

    The patch looks wrong to me: __NR_io_pgetevents_time64 must be used
    whenever time_t is 64-bit wide on a 32-bit architecture, while
    __NR_io_getevents/__NR_io_pgetevents must be used when time_t is the
    same width as 'long'.

    Checking whether __NR_io_getevents is defined is wrong for all
    architectures other than riscv

And in light of the above, indeed the patch does not look so correct
after all.
