[BUG] 4.99.0 - Installs liblsof.a even when --disable-static is mentioned

[subnut]

Describe the bug
configure --disable-static --disable-shared should result in neither the static nor the shared libraries to be installed. And since the libraries aren't being installed, the header files shouldn't be installed either.

Currently, it behaves as if --disable-static was never mentioned, i.e. installing both liblsof.a and the header files (lsof.h, lsof_fields.h)

To Reproduce
Steps to reproduce the behavior:

1. Download and extract https://github.com/lsof-org/lsof/releases/download/4.99.0/lsof-4.99.0.tar.gz
2. Run configure --enable-security --disable-static --disable-shared
3. make
4. make install

Expected behavior
Libraries and Header files not being installed

Actual behaviour
Static library is installed. Header files are installed

Environment (please complete the following information):

• Kernel: Linux 6.5.11
• OS: Void Linux
• lsof Version: 4.99.0
• Origin: built from release tarball

Additional context
Add any other context about the problem here.

It seems to be a limitation of libtool. Can we workaround it?

I've tried my hand at a possible workaround in #300

This is my first time interacting with autoconf/automake, so there may be mistakes..
