perf trace: Use strtoul for the fcntl 'cmd' argument
Since its values are in two ranges of values we ended up codifying it
using a 'struct strarrays', so now hook it up with STUL_STRARRAYS so
that we can do:
# perf trace -e syscalls:*enter_fcntl --filter=cmd==SETLK||cmd==SETLKW
0.000 sssd_kcm/19021 syscalls:sys_enter_fcntl(fd: 13</var/lib/sss/secrets/secrets.ldb>, cmd: SETLK, arg: 0x7ffcf0a4dee0)
1.523 sssd_kcm/19021 syscalls:sys_enter_fcntl(fd: 13</var/lib/sss/secrets/secrets.ldb>, cmd: SETLK, arg: 0x7ffcf0a4de90)
1.629 sssd_kcm/19021 syscalls:sys_enter_fcntl(fd: 13</var/lib/sss/secrets/secrets.ldb>, cmd: SETLK, arg: 0x7ffcf0a4de90)
2.711 sssd_kcm/19021 syscalls:sys_enter_fcntl(fd: 13</var/lib/sss/secrets/secrets.ldb>, cmd: SETLK, arg: 0x7ffcf0a4de70)
