meson: build Linux-PAM using meson

On my non-representative hardware, the full build using autotools
(./autogen.sh && CFLAGS=-O2 ./configure && make -j`nproc` && make -j`nproc` install)
takes about 45 seconds.

On the same hardware, the full build using meson
(meson setup -Doptimization=2 dir && meson compile -C dir && meson install -C dir)
takes just about 7.5 seconds.
