swtpm: Check for defined __SNR_MOUNT_setattr and __NR_mount_setattr

Address the following compilation error on Debian:

In file included from /usr/include/seccomp.h:821,
                 from seccomp_profile.c:44:
seccomp_profile.c: In function 'create_seccomp_profile':
seccomp_profile.c:115:9: error: '__NR_mount_setattr' undeclared (first use in this function)
  115 |         SCMP_SYS(mount_setattr),
      |         ^~~~~~~~
seccomp_profile.c:115:9: note: each undeclared identifier is reported only once for each function it appears in
seccomp_profile.c:172:9: error: '__NR_quotactl_fd' undeclared (first use in this function)
  172 |         SCMP_SYS(quotactl_fd),
      |         ^~~~~~~~

We need to do this since they are defined like this:

 #define __SNR_mount_setattr             __NR_mount_setattr
 #define __SNR_quotactl_fd               __NR_quotactl_fd
