sqlite3: Avoid rpath; tweak install name

[ryandesign]

Description

Don't use -rpath since it's never needed and causes an error with older compilers.

Closes: https://trac.macports.org/ticket/72018

Change the install name from /opt/local/lib/libsqlite3.dylib back to /opt/local/lib/libsqlite3.0.dylib as it was in 3.48.0 and earlier.

Change the install name in post-build not post-destroot and use shellescape when doing so.

See: https://trac.macports.org/ticket/72021

Ryan,

First of all, many thanks for helping to get this critical package back!

I hadn't seen this PR when I went in to deal with shellescape and to add the note.

[Schamschula]

I'm good with this!

Sorry about the duplicated work! I thought I could get mine done before you had started on anything.
