FindPkgConfig: do not always rerun pkg_check_modules() with 2 arguments
Since commit v3.8.0-rc1~47^2 (FindPkgConfig: Recheck pkg-config on
parameter change, 2017-01-17) calling `pkg_check_modules` always
re-runs. The problem is that if there are only 2 arguments passed to
`pkg_check_modules```, then `_module0` will be set and `ARGN` will be
empty. When this is written to cache it will be stored as just the
value of `_module0` without any semicolon, so on the next run this
doesn't match the expected value and the search is rerun.
Revise the logic to handle the case of empty `ARGN` separately.
Fixes: #17003
