prov/hook: add include of prov/hook/perf/include to ofi_hook_profile if configured as DSO

[philippfriese]

If the ofi_hook_profile provider is configured as a loadable library, then the file hook_perf.h will not be found during compilation:

$ ./configure --enable-profile=dl
[...]
***
*** Built-in providers:	lnx dmabuf_peer_mem hook_hmem hook_debug monitor trace perf sm2 shm rxd mrail rxm tcp udp sockets
*** DSO providers:	profile
***
$ make 
[...]
In file included from prov/hook/profile/src/hook_profile.c:36:
./prov/hook/include/hook_prov.h:14:10: fatal error: hook_perf.h: No such file or directory
   14 | #include "hook_perf.h"
      |          ^~~~~~~~~~~~~
compilation terminated.

This file is transitively included via hook_prov.h:14 in hook_profile.c:36. The #if HAVE_PERF check passes by default since ofi_hook_perf is built by default.

This PR adds the missing include of prov/hook/perf/include in case the ofi_hook_profile provider is configured as a DSO.
