linux/musl: Make time_t and suseconds_t 64-bit on all musl platforms

[kraj]

time_t and suseconds_t are defined as 64-bit quanity on musl systems regardless of 32bit or 64bit CPU word length

grep "_Int64" in musl tree shows this

arch/aarch64/bits/alltypes.h.in:#define _Int64 long arch/arm/bits/alltypes.h.in:#define _Int64 long long arch/i386/bits/alltypes.h.in:#define _Int64 long long arch/loongarch64/bits/alltypes.h.in:#define _Int64 long arch/m68k/bits/alltypes.h.in:#define _Int64 long long arch/microblaze/bits/alltypes.h.in:#define _Int64 long long arch/mips/bits/alltypes.h.in:#define _Int64 long long arch/mips64/bits/alltypes.h.in:#define _Int64 long arch/mipsn32/bits/alltypes.h.in:#define _Int64 long long arch/or1k/bits/alltypes.h.in:#define _Int64 long long arch/powerpc/bits/alltypes.h.in:#define _Int64 long long arch/powerpc64/bits/alltypes.h.in:#define _Int64 long arch/riscv32/bits/alltypes.h.in:#define _Int64 long long arch/riscv64/bits/alltypes.h.in:#define _Int64 long arch/s390x/bits/alltypes.h.in:#define _Int64 long

Checklist

• Relevant tests in libc-test/semver have been updated
• No placeholder or unstable values like *LAST or *MAX are
  included (see #3131)
• Tested locally (cd libc-test && cargo test --target mytarget);
  especially relevant for platforms that may not be checked in CI

Unfortunately this isn't just a trivial incorrect type; we also need to use the new link names when the 1.2 definitions are used. There is a work in progress at #4463.

yeah I did realize it after some testing. We need to keep the underlying types matches with musl, so perhaps c_long and c_longlong based upon architecture would be right thing to do.

I'm going to close this since it should be covered by #4463.
