mremap support for Solaris

Oracle Solaris SRU 45 (May 2022) introduced a new mremap syscall that behaves the same as on Linux. The attached patch adds support for it; without it, Valgrind fails to build when mremap is available with:

m_aspacemgr/aspacemgr-common.c:234:6: error: #error Unknown OS
  234 | #    error Unknown OS
      |

To be sure, I ran `build` and `test` on illumos/OpenIndiana (which doesn't have mremap syscall) and found no issues with this patch.
