build: Fix make distcheck for input plugin

suspend.c is a symlink generated at build time, therefore it should be
created on build directory. Additionally, it is necessary to add
-I$(srcdir)/profiles/input to CPPFLAGS so suspend.h can be found (the
compiler does not follow symlinks prior to resolving #include
directives).
