elf: Add glibc version dependency only if needed

There is no need to add a needed glibc version if the glibc base version
includes the needed glibc version.

	PR ld/31966
	* elflink.c (elf_link_add_glibc_verneed): Add glibc_minor_base.
	Skip if the glibc base version includes the needed glibc version.
	(_bfd_elf_link_add_glibc_version_dependency): Initialize
	glibc_minor_base to INT_MAX and pass it to
	elf_link_add_glibc_verneed.
