linux-user: Fix fcntl64() and accept4() for 32-bit targets

A set of 3 patches:
The first two patches fix fcntl64() and accept4().
the 3rd patch enhances the strace output for pread64/pwrite64().

This pull request does not includes Richard's mmap2 patch:
https://patchew.org/QEMU/20230630132159.376995-1-richard.henderson@linaro.org/20230630132159.376995-12-richard.henderson@linaro.org/

Changes:
v3:
- added r-b from Richard to patches #1 and #2
v2:
- rephrased commmit logs
- return O_LARGFILE for fcntl() syscall too
- dropped #ifdefs in accept4() patch
- Dropped my mmap2() patch (former patch #3)
- added r-b from Richard to 3rd patch
