[File] [PATCH 1/2] seccomp: undef pread64 to fix the build with musl

[Yegor Yefremov]

Since 5.48, seccomp.c includes <unistd.h>. With _LARGEFILE64_SOURCE,
musl's unistd.h does

  #define pread64 pread

which turns ALLOW_RULE(pread64) into SCMP_SYS(pread), which does not
exist:

  seccomp.c:53:52: error: '__SNR_pread' undeclared (first use in this function)

Undefine the macro before using it. The same musl issue affects
fstatat64 (bug 473).
