missing_fcntl: drop definitions covered by glibc-2.31

Browse Source 
Note, this also fixes the definition for O_TMPFILE for parisc and hppa,
it should be 040000000 (seven zeros) rather than 0400000000 (eight zeros).

/* So O_LARGEFILE is generally implied by glibc, and defined to zero hence, because we only build in LFS
