meson: drop all unused bits from configure.ac

AC_CANONICAL_HOST adds --host option to configure which is provided
automatically by Meson as --cross-file.

All of the AC_PROG_CC, AC_PROG_INSTALL, AC_PROG_CPP, AM_PROG_CC_C_O,
AM_PROG_LD, PKG_PROG_PKG_CONFIG are automatically checked by Meson.

libtool is not used by meson so there is no need for that as well and
the remaining directives are not relevant for Meson.
