firebird: set -mmacosx-version-min to 10.15

Building on macOS Sonoma fails when this flag is set to 10.9 or
is unset. But setting this flag to 10.15 which matches the lowest
-mmacosx-version-min that LibreOffice builds with on Mac Intel
avoids all of the new deprecation warnings that turn into errors
that started with Xcode 14.

Also, fix runtime failure, at least on macOS, when the firebird
build runs the isql command by adding $(firebird_BUILDDIR)/lib to
LIBO_TUNNEL_LIBRARY_PATH.
