[committed] Fix installation of man page from separate builddir

[Tom de Vries <tdevries@suse.de>]

Hi,

When doing make install in a separate build dir, we run into:
...
$ make install DESTDIR=$(pwd -P)/../install
make -f /data/dwz/dwz.git/Makefile srcdir=/data/dwz/dwz.git install
make[1]: Entering directory '/data/dwz/build'
install -D dwz /data/dwz/build/../install/usr/bin/dwz
install -D -m 644 dwz.1 /data/dwz/build/../install/usr/share/man/man1/dwz.1
install: cannot stat 'dwz.1': No such file or directory
make[1]: *** [/data/dwz/dwz.git/Makefile:19: install] Error 1
make[1]: Leaving directory '/data/dwz/build'
make: *** [Makefile:7: install] Error 2
...

Fix this by prefixing dwz.1 with $(srcdir)/ in the install command.

Committed to trunk.

Thanks,
- Tom
