Subject: [PATCH] meson.build: use dependency function for readline

Use meson dependency function to find readline instead of
cc.find_library. This function will retrieve readline pkg-config file
which is available since version 7 (released 5 years ago) and
https://git.savannah.gnu.org/cgit/readline.git/commit/readline.pc.in?id=d49a9082c0e15bba8cd3d8cc0a994409cf823cac.
readline.pc sets tinfo in Requires.Private which will avoid the
following static build failure:

/home/buildroot/autobuild/instance-1/output-1/host/opt/ext-toolchain/bin/../lib/gcc/i586-buildroot-linux-musl/9.3.0/../../../../i586-buildroot-linux-musl/bin/ld: /home/buildroot/autobuild/instance-1/output-1/host/i586-buildroot-linux-musl/sysroot/usr/lib/libreadline.a(display.o): in function `_rl_move_cursor_relative':
display.c:(.text+0xbb5): undefined reference to `tputs'
