Bug#473211: libgtop2: FTBFS on GNU/kFreeBSD - cleaner Makefile.am

[Petr Salinger]

The following snippet of sysdeps/common/Makefile.am
also works on kfreebsd:

if !LIBGTOP_SYSDEPS_PRIVATE_MOUNTLIST
mountlist_src = mountlist.c
endif

if !LIBGTOP_SYSDEPS_PRIVATE_FSUSAGE
fsusage_src = fsusage.c
endif

libgtop_common_2_0_la_SOURCES   = error.c gnuslib.c \
                                   procargs.c \
                                   default.c \
                                   $(mountlist_src) $(fsusage_src)

Please, could you forward it upstream for inclusion in 2.22.1
