man: Collect names of man pages automatically

As it turned out, forgetting to add a man page to the respective
Makefile when introducing it is a common mistake. Overcome this once and
for all by using $(wildcard) function in Makefiles.

Fixes: 7124942942 ("genl: add manpage")
Fixes: 958cd21094 ("ifcfg: add manpage")
Fixes: e1b7f883e5 ("man: add documentation for IPv6 SR commands")
Fixes: 1949f82cdf ("Introduce ip vrf command")
Fixes: 535194a172 ("tipc: add peer remove functionality")
