Make termcap.c implementations consistent with tparam.h prototypes.

 src/termcap.c [MSDOS]: Include "msdos.h.
 (find_capability, tgetnum, tgetflag, tgetstr, tputs, tgetent):
 Constify `char *' arguments and their references according to
 prototypes in tparam.h.
 src/deps.mk (termcap.o): Depend on tparam.h and msdos.h.
