  Log Message:
  -----------
  [lldb] [POSIX-DYLD] Add libraries from initial rendezvous brkpt hit

Explicitly consider the libraries reported on the initial rendezvous
breakpoint hit added.  This is necessary on FreeBSD since the dynamic
loader issues only a single 'consistent' state rendezvous breakpoint hit
for all the libraries present in DT_NEEDED.  It is also helpful on Linux
where it ensures that ld-linux is considered loaded as well
as the shared system libraries reported afterwards.

Reenable memory maps on FreeBSD since this fixed the issue triggered
by them.

  Log Message:
  -----------
  [lldb] [POSIX-DYLD] Update the cached exe path after attach

Fix the POSIX-DYLD plugin to update the cached executable path after
attaching.  Previously, the path was cached in DYLDRendezvous
constructor and not updated afterwards.  This meant that if LLDB was
attaching to a process (e.g. via connecting to lldb-server), the code
stored the empty path before DidAttach() resolved it.  The fix updates
the cached path in DidAttach().

This fixes a new instance of https://llvm.org/pr17880
