maint: remove unnecessary ignore_value usage

* src/install.c: Remove ignore-value.h include.
(strip): Don't use ignore_value on posix_spawnattr_destroy since it
isn't declared with the warn_unused_result attribute. Pass the checked
pointer to posix_spawnattr_destroy instead of the variable it points to.
