elf: Add support for GNU_PROPERTY_NO_MEMORY_SEALazanella/mseal
The GNU_PROPERTY_NO_MEMORY_SEAL is a GNU property per module instructing
the glibc not to seal the object PT_LOAD. It can be used for any reason
the modules require to seal not to be enabled (i.e., on Firefox hack to
bypass the dynamic loader and enable DT_RELR on older glibc [1]). In
this case, it is up to the module to apply memory sealing itself.
The sealing is applied by default, and it is always enforced with
glibc.rtld.seal=2.
Checked on aarch64-linux-gnu, x86_64-linux-gnu, and
powerpc64le-linux-gnu.
