swtpm: Fixed typo `fs_mount` vs `fsmount` and removed duplicates.

The project wouldn't compile on my ubuntu 20.04.1 based system with the error message:
```
  CC       libswtpm_libtpms_la-seccomp_profile.lo
In file included from seccomp_profile.c:44:
seccomp_profile.c: In function ‘create_seccomp_profile’:
seccomp_profile.c:105:9: error: ‘__SNR_fs_mount’ undeclared (first use in this function)
  105 |         SCMP_SYS(fs_mount),
      |         ^~~~~~~~
seccomp_profile.c:105:9: note: each undeclared identifier is reported only once for each function it appears in
```

Additionally, there were some duplicates in the profile.
