alpm_initialize: Fix double slash in sys hook dir path

Browse Source 
The path of the default system hook directory was created
by concatenating `myhandle->root` (usually "/"), and
SYSHOOKDIR (usually "/usr/share/libalpm/hooks/"), resulting
in "//usr/share/libalpm/hooks/". Fix this by skipping the
initial slash from SYSHOOKDIR.
