libpacman: Do strip all symbols from EXEs and DLLs

[lhmouse]

This matches the case for 'EXEC (Executable file)' below.

Passing --strip-all instead of --strip-unneeded to strip can make installed executables a bit smaller. For example, stripping all symbols from /mingw64/bin/gcc.exe can reduce its size from 2,351,500 to 2,344,448 (-7,052).

Microsoft documentation also suggests that there should be no symbol in PE files; see references about PointerToSymbolTable and NumberOfSymbols.

Since I never responded here:

• I'd still like to have some docs for listing imports/exports etc in the MSYS2 docs or something, so we can point users to that. I try to get to that some time..

And I think someone on IRC suggested back then, that the stripped information here could in theory be used to debug pseudo relocations, and there is no replacement information for that. Not that we use that anywhere right now, but something to consider.

I think this can be closed for now.
