Remove bogus check for too many program headers
This test appears bogus because the e_phnum element of Elf32_Phdr and
is an unsigned 16bit entity.
This addresses the following warnings:
vmcore-dmesg/vmcore-dmesg.c: In function 'read_elf32':
vmcore-dmesg/vmcore-dmesg.c:116: warning: comparison is always false due to limited range of data type
vmcore-dmesg/vmcore-dmesg.c: In function ‘read_elf64’:
vmcore-dmesg/vmcore-dmesg.c:192: warning: comparison is always false due to limited range of data type
