Replace psymbol_allocation_list with std::vector

psymbol_allocation_list is basically a vector implementation.  We can
replace it with an std::vector, now that objfile has been C++-ified.

I sent this to the buildbot, there are a few suspicious failures, but
I don't think they are related to this patch.  For example on powerpc:

new FAIL: gdb.base/catch-syscall.exp: execve: syscall execve has returned
new FAIL: gdb.base/catch-syscall.exp: execve: continue to main
new FAIL: gdb.base/catch-syscall.exp: execve: continue until exit

I get the same failures when testing manually on gcc112, without this
patch.
