meson: Use cc.compiles instead of cc.has_header to check malloc.h

Browse Source 
cc.has_header checks whether a header exists without knowing whether it
can be used. This is a problem on FreeBSD because its malloc.h is a
header with an '#error' line which always throw compilation error. To
avoid false positive in the check result, we use cc.compiles to do a
full compilation test instead of cc.has_header which only does check
with preprocessor.
